A nice Visual Diagram is there on the SERVER CLIENT concept. Must see for newbie.
PHP is a server-side scripting language used for web development. It allows developers to embed PHP code into HTML pages which is then interpreted and executed by a PHP processor on the server to generate dynamic web pages. PHP code is contained within special tags and can be used to store and retrieve data from databases, create forms, send emails, and more. Some key PHP features include variables, functions, object-oriented capabilities, and file uploads. The php.ini configuration file controls aspects of PHP's behavior.
The document discusses HTML tags and PHP. It provides an introduction to PHP including what PHP is, how PHP files work, what PHP can do, and why PHP is useful. It also covers basic PHP syntax, variables, echo and print statements, and variable scope.
The document provides syntax and descriptions for various Linux commands including bc, cal, cat, cd, cp, date, echo, grep, id, last, lastlog, ls, man, mkdir, mv, pwd, rm, rmdir, sort, shutdown, who, whois, more, less, clear, cmp, wc, whoami, head, and tail. It explains what each command is used for and provides the basic syntax.
CSS (Cascading Style Sheets) allows adding layout and design to websites in a new way and is essential for web design. CSS can be applied to HTML elements inline using the style attribute, or internally using the <style> tag placed in the <head> section. For example, to make the page background red with CSS, the code "body {background-color: #FF0000;}" can be placed within <style> tags or applied directly to the <body> element's style attribute.
Apache is an open-source web server software that is very popular, secure, fast and reliable. It became the first web server to serve over 100 million websites. Apache relies on text configuration files like httpd.conf to manage settings and is run from the command line using a control script. It supports features like SSL, virtual hosts and CGI and can be installed on Linux, Unix and Windows systems.

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

4. PHP stands for Hypertext Preprocessor and is a server-side language. This means that the script is run on your web server, not on the user's browser, so you do not need to worry about compatibility issues. PHP is relatively new (compared to languages such as Perl (CGI) and Java) but is quickly becoming one of the most popular scripting languages on the INTERNET. INTRODUCTION
5. WRITING PHP Writing PHP on your computer is actually very simple. You don't need any special software, except for a text editor (like Notepad in Windows). Run this and you are ready to write your first PHP script.
6. DECLARING PHP PHP scripts are always enclosed in between two PHP tags. This tells your server to parse the information between them as PHP. The three different forms are as follows: <? PHP Code In Here ?>
8. To output text in your PHP script is actually very simple. . The main one you will be using, though, is print. Print will allow you to output text, variables or a combination of the two so that they display on the screen. EXAMPLE: <? print("Hello world!"); ?> Which will display: Hello world! on the screen. PRINTING TEXT
9. VARIABLES As with other programming languages, PHP allows you to define variables. In PHP there are several variable types, but the most common is called a String. It can hold text and numbers. All strings begin with a $ sign. To assign some text to a string you would use the following code: $welcome_text = "Hello and welcome to my website."; This is quite a simple line to understand, everything inside the quotation marks will be assigned to the string.
10. OUTPUTING VARIABLES To display a variable on the screen uses exactly the same code as to display text but in a slightly different form. The following code would display your welcome text: <? $welcome_text = "Hello and welcome to my website."; print($welcome_text); ?>
11. FORMATTING THE TEXT Formatting the text in PHP includes the color in codes and not in namesFor this example I will change the text to the Arial font in red. The normal code for this would be: <font face="Arial" color="#FF0000"></font> You can now include this in your print statement: print("<font face=amp;quot;Arialamp;quot; coloramp;quot;#FF0000amp;quot;>Hello and welcome to my website.</font>"); which will make the browser display: Hello and welcome to my website.
12. If statements are used to compare two values and carry out different actions based on the results of the test. If statements take the form IF, THEN, ELSE. Basically it checks the condition. If it is true, the then statement is executed. If not, the else statement is executed. The structure of an IF statement is as follows: IF (something == something else) {THEN Statement } else { ELSE Statement} THE BASIC IF STRUCTURE
13. VARIABLES IN IF STATEMENT The most common use of an IF statement is to compare a variable to another piece of text, a number, or another variable. For example: if ($username == "webmaster") which would compare the contents of the variable to the text string. The THEN section of code will only be executed if the variable is exactly the same as the contents of the quotation marks so if the variable contained 'Web master' or 'WEBMASTER' it will be false.
14. CONSTRUCTING THEN To add to your script, you can now add a THEN statement: if ($username == "webmaster") { echo "Please enter your password below";} This will only display this text if the username is webmaster. If not, nothing will be displayed. You can actually leave an IF statement like this, as there is no actual requirement to have an ELSE part. This is especially useful if you are using multiple IF statements.
15. CONSTRUCTING ELSE Adding The ELSE statement is as easy as the THEN statement. Just add some extra code: if ($username == "webmaster") { echo "Please enter your password below"; } else { echo "We are sorry but you are not a recognized user";} Of course, you are not limited to just one line of code. You can add any PHP commands in between the curly brackets. You can even include other IF statements (nested statements).
16.
17. WHILE STATEMENT If you have a piece of code which you want to repeat several times without retyping it, you can use a while loop. For instance if you wanted to print out the words "Hello World" 5 times you could use the following code: $times = 5; $x = 0; while ($x < $times) { echo "Hello World"; ++$x;}
18. USING $X The variable counting the number of repeats ($x in the above example) can be used for much more than just counting. For example if you wanted to create a web page with all the numbers from 1 to 1000 on it, you could either type out every single one or you could use the following code: $number = 1000; $current = 0; while ($current < $number) { ++$current; echo "$current<br>";}
19. ARRAY Arrays are common to many programing languages. They are special variables which can hold more than one value, each stored in its own numbered 'space' in the array. Arrays are extremely useful, especially when using WHILE loops.
20. TYPES OF ARRAY In PHP, there are three kind of arrays: * Numeric array - An array with a numeric index * Associative array - An array where each ID key is associated with a value * Multidimensional array - An array containing one or more arrays
21. SETTING UP AN ARRAY Setting up an array is slightly different to setting up a normal variable. In this example I will set up an array with 5 names in it: $names[0] = 'John'; $names[1] = 'Paul'; $names[2] = 'Steven'; As you can see, the parts of an array are all numbered, starting from 0. To add a value to an array you must specify the location in the array by putting a number in [ ].
22. PHP WITH FORMS Setting up a form for use with a PHP script is exactly the same as normal in HTML. As this is a PHP tutorial I will not go into depth in how to write your form but I will show you three of the main pieces of code you must know: <input type="text" name="the box" value="Your Name"> Will display a text input box with Your Name written in it as default. The value section of this code is optional. The information defined by name will be the name of this text box and should be unique. <textarea name="message"> Please write your message here. </textarea> Will display a large scrolling text box with the text 'Please write your message here.' as default. Again, the name is defined and should be unique. <input type="submit" value="Submit"> This will create a submit button for your form. You can change what it says on the button by changing the button's value.
23. GET METHOD The built-in $_GET function is used to collect values from a form sent with method="get". Information sent from a form with the GET method is visible to everyone (it will be displayed in the browser's address bar) and has limits on the amount of information to send (max. 100 characters). Example <form action="welcome.php" method="get"> Name: <input type="text" name="fname" /> Age: <input type="text" name="age" /> <input type="submit" /></form> When the user clicks the "Submit" button, the URL sent to the server could look something like this: http://www.w3schools.com/welcome.php?fname=Peter&age=37 The "welcome.php" file can now use the $_GET function to collect form data (the names of the form fields will automatically be the keys in the $_GET array): Welcome <?php echo $_GET["fname"]; ?>.<br /> You are <?php echo $_GET["age"]; ?> years old!
24. POST METHOD The built-in $_POST function is used to collect values from a form sent with method="post".Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.Example <form action="welcome.php" method="post"> Name: <input type="text" name="fname" /> Age: <input type="text" name="age" /> <input type="submit" /></form> When the user clicks the "Submit" button, the URL will look like this: http://www.w3schools.com/welcome.php The "welcome.php" file can now use the $_POST function to collect form data (the names of the form fields will automatically be the keys in the $_POST array): Welcome <?php echo $_POST["fname"]; ?>!<br /> You are <?php echo $_POST["age"]; ?> years old.
25. READING FROM AN ARRAY Reading from an array is just the same as putting information in. All you have to do is to refer to the array and the number of the piece of data in the array. So if I wanted to print out the third name I could use the code: echo "The third name is $names[2]"; Which would output: The third name is Steven
26. PHP FUNCTIONS In PHP, there are more than 700 built-in functions. This chapter shows how to create your own functions. A function will be executed by a call to the function. You may call a function from anywhere within a page. Syntax: function functionName() { code to be executed; }
28. Mail is extremely easy to send from PHP, unlike using scripting languages which require special setup (like CGI). There is actually just one command, mail() for sending mail. It is used as follows: mail($to,$subject,$body,$headers); In this example I have used variables as they have descriptive names but you could also just place text in the mail command. Firstly, $to. This variable (or section of the command) contains the e-mail address to which the mail will be sent. $subject is the section for the subject of the e-mail and $body is the actual text of the e-mail.The section $headers is used for any additional e-mail headers you may want to add. The most common use of this is for the From field of an e-mai but you can also include other headers like cc and bcc. MAIL COMMAND
29. SENDING MAIL Before sending your mail, if you are using variables, you must, of course, set up the variable content beforehand. Example: $to = "php@gowansnet.com"; $subject = "PHP Is Great"; $body = "PHP is one of the best scripting languages around"; $headers = "From: webmaster@gowansnet.com"; mail($to,$subject,$body,$headers); echo "Mail sent to $to"; This code will acutally do two things. Firstly it will send a message to php@gowansnet.com with the subject 'PHP Is Great' and the text: PHP is one of the best scripting languages around and the e-mail will be from webmaster@gowansnet.com. It will also output the text: Mail sent to php@gowansnet.com
30. ERROR CONTROL As anyone who has been scripting for a while will know, it is extremely easy to make mistakes in your code and it is also very easy to input an invalid e-mail address (especially if you are using your script for form to mail). Because of this, you can add in a small piece of code which will check if the e-mail is sent: if(mail($to,$subject,$body,$headers)) { echo "An e-mail was sent to $to with the subject: $subject";} else { echo "There was a problem sending the mail. Check your code and make sure that the e-mail address $to is valid";} This code is quite self explanatory If the mail is sent successfully it will output a message to the browser telling the user, if not, it will display an error message with some suggestions for correcting the problem.
31. PHP INSTALLATION The Windows PHP installer is available from the downloads page at » http://www.php.net/downloads.php. This installs the CGI version of PHP and for IIS, PWS, and Xitami, it configures the web server as well. The installer does not include any extra external PHP extensions (php_*.dll) as you'll only find those in the Windows Zip Package and PECL downloads. First, install your selected HTTP (web) server on your system, and make sure that it works. Run the executable installer and follow the instructions provided by the installation wizard. Two types of installation are supported - standard, which provides sensible defaults for all the settings it can, and advanced, which asks questions as it goes along. The installation wizard gathers enough information to set up the php.ini file, and configure certain web servers to use PHP. One of the web servers the PHP installer does not configure for is Apache, so you'll need to configure it manually. Once the installation has completed, the installer will inform you if you need to restart your system, restart the server, or just start using PHP.
32. PHP INI FILE Since PHP 5.3.0, PHP includes support for .htaccess-style INI files on a per-directory basis. These files are processed only by the CGI/FastCGI SAPI. This functionality obsoletes the PECL htscanner extension. If you are using Apache, use .htaccess files for the same effect. In addition to the main php.ini file, PHP scans for INI files in each directory, starting with the directory of the requested PHP file, and working its way up to the current document root (as set in $_SERVER['DOCUMENT_ROOT']). Only INI settings with the modes PHP_INI_PERDIR and PHP_INI_USER will be recognized in .user.ini-style INI files. Two new INI directives, user_ini.filename and user_ini.cache_ttl control the use of user INI files. user_ini.filename sets the name of the file PHP looks for in each directory; if set to an empty string, PHP doesn't scan at all. The default is .user.ini. user_ini.cache_ttl controls how often user INI files are re-read. The default is 300 seconds (5 minutes).
