How to Create Login and Registration API in PHP.pdfAppweb Coders
In today’s article, we will explore the concept of REST API and delve into creating a login and registration system using these APIs. In the contemporary landscape of web development, establishing strong and secure authentication systems is of utmost significance. A highly effective approach is to construct a Login and Registration system through the utilization of REST APIs. This article aims to provide you with a comprehensive walkthrough, enabling you to construct a robust and efficient user authentication system from the ground up, harnessing the capabilities of REST architecture.
REST (Representational State Transfer) APIs act as a bridge between the client and the server, facilitating effective communication between them. They utilize HTTP requests to transfer data and are an optimal choice for constructing systems due to their stateless nature. REST APIs provide a seamless integration experience across a variety of platforms and devices.
Before we start coding, ensure you have a development environment set up. Install a web server (e.g., Apache), PHP, and a database (such as MySQL). Organize your project directory and create separate folders for PHP files, configurations, and assets.
Note: In this tutorial, we are utilizing PDO for all database operations. If you are interested in learning about using MySQL or MySQLi, please leave a comment indicating your preference. I will either update this tutorial or create a new article on that topic as well.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

https://www.microsoft.com/en-us/research/blog/graphrag-unlocking-llm-discovery-on-narrative-private-data/
2. What is PHP?
PHP (recursive acronym for "PHP:
Hypertext Preprocessor") is a widely-used
Open Source general-purpose scripting
language that is especially suited for Web
development and can be embedded into
HTML.
<? echo “HI!”; ?>
3. What is PHP?
Compared to others like:
Java – Sun, compiled and interpreted (jsp)
Perl – Open Source, scripting
.NET – MS, opposite of Java
ColdFusion – Now Adobe, the original
Javascript – Netscape, client-side
PHP – Open Source, server-side
4. How it works
PHP is installed on web server
Our web server is Apache (just an FYI)
Server parses files based on extensions
Returns plain HTML, no code
5. How To – The Basics
Need to name files is a .php extension
Example: index.php, mypage.php
Open and close tags: <? ?>
Was: <?php ?>
Save file to server, view in a browser
8. Variables
In PHP, you create a variable with a dollar
sign and some text.
Usually the text will be something descriptive
of what it is going to hold.
$name = “Patrick Laverty”;
$dept = “CIS”;
$campus_addr = “Box 1885”;
11. Array Variables
Hold multiple values
All in one step example:
$kids = Array(“Tom”,”Dick”,”Harry”);
Multiple steps example:
$kids = Array();
$kids[0] = “Tom”;
$kids[1] = “Dick”;
$kids[2] = “Harry”;
Individual array values are just a scalar
12. Array Variables
Associative Arrays – may be easier to find
stuff
$teams = Array(‘bos’=>’Red Sox’,
‘nyy’=>’Yankees’, ’bal’=>’Orioles’);
The two-step way works the same:
$teams = Array();
$teams[‘bos’] = ‘Red Sox’;
15. Functions
Be lazy. It’s a good thing.
If you’re going to do the same action more
than once, write a function.
sayhello.php
function sayHello($toWhom)
{
echo “Hello $toWhom”;
}
16. Functions
Lots have already been written for you:
http://php.net/manual/en
If you know the function:
http://php.net/echo
17. A Basic Form
How we do things now: eform.cgi
<form method=“POST” action=
http://www.brown.edu/cgi-local/eform.cgi>
<input type=“text” name=“name”>
<input type=“text” name=“age”>
<input type=“submit”>
</form>
18. A Basic Form
How we do things with PHP:
basicform.html
<form method=“POST” action=“output.php”>
<input type=“text” name=“name”>
<input type=“text” name=“age”>
<input type=“submit”>
</form>
19. A Basic Form
Capturing the data in output.php
Variables:
$_POST[‘name’]
$_POST[‘age’]
Use phpinfo() to see variables
20. A Basic Form
Weave HTML and PHP
output.php
<html><body>
<?
$name = $_POST[‘name’];
$age = $_POST[‘age’];
echo “My name is $name and I am $age years old”;
?>
</body></html>
22. A Basic Form
Outputting to the screen is nice, but boring
We could email the results
Let’s store data in a database
23. Layers of a Database
Server
Database
Tables
Fields/Columns
Records
Data
24. How to Get a Database
Use Microsoft Access
Use Filemaker
Request a MySQL Database
(http://brown.edu/db)
25. Request a MySQL Database
You will receive:
Server name (it’s not localhost)
Database name
Username
Password
Link to phpMyAdmin
26. phpMyAdmin
phpMyAdmin is a graphical view of your
database
Very easy
Let’s take a look
(http://brown.edu/phpMyAdmin)
27. Connecting to DB from PHP
Create one connection script:
dbconn.php
<?
$conn = mysql_connect($server,$user,$pw);
mysql_select_db($db,$conn);
?>
28. Connecting to DB from PHP
Remember, “Be Lazy!”
At the top of each file that needs the DB:
<? require(“dbconn.php”); ?>
29. Database Table
Table named ‘info’ has two fields, name and age
Use a SQL INSERT statement:
$sql =
“INSERT INTO
info (name,age)
values (‘$name’, ‘$age’)”;
31. The Whole Picture
dbinsert.php
<? require(“dbconn.php”);
$name = $_POST[‘name’];
$age = $_POST[‘age’];
$sql = “INSERT into info (name,age) values(‘$name’, ‘$age’);”
mysql_query($sql,$conn);
?>
<html><body>
Thank you, your name and age were received.
</body></html>
32. The Whole Picture - Fancier
fancydbinsert.php
<? require(“dbconn.php”);
$name = $_POST[‘name’];
$age = $_POST[‘age’];
$sql = “INSERT into info (name,age) values(‘$name’, ‘$age’);”
$success = mysql_query($sql,$conn);
?>
<html><body>
<? if($success)
{ echo “Thank you, your name and age were received.”; }
else
{ echo “Sorry, your info wasn’t received, please contact …”; }
?>
</body></html>
33. Getting the Info Back
Read it in phpMyAdmin
Create an output page
(Just like that little survey you filled out)
34. Create an Output Page
Connect to the Server
Do a query of the data
Programmatically write the data to a page
View the page in a browser
Let’s see how to do it
35. Connect to the Server
First, include our connection script:
<? require(“dbconn.php”); ?>
36. Do a Query of the Data
This time we use SELECT
$sql = “SELECT name, age FROM info”;
Or if you have many fields and want to be LAZY!
$sql = “SELECT * from info”;
37. Programmatically Write the Data
Here’s the only hard part:
<table border=“1”>
<? $result = mysql_query($sql, $conn);
while($table = mysql_fetch_object($result))
{
echo “<tr><td>”;
echo $table->name;
echo “</td><td>”;
echo $table->age;
echo “</td></tr>”;
}
?>
</table>
42. One Helpful Function
nl2br() – Line breaks in a form are not
respected
This function will turn a newline (nl) character
into (2) an html <br> (br) tag.
43. Data Validation
Very Important!
Without it, your site and all others can be
hacked!
PHP makes it easier
44. Data Validation
Cut down on XSS with htmlentities()
Cut down on SQL-injection with
mysql_real_escape_string()
Check that you’re getting what you expect
Check that you’re getting the length you
expect
Don’t trust JavaScript
45. Data Validation
Cross site scripting vulnerability
Allows a user to input scripts
Allows a user to input links to malicious sites
Allows a user to steal a
session/cookie/password
The htmlentities() function turns entities into
its harmless entity number.
A ‘ is turned into '
46. Data Validation
SQL-injection vulnerability
Allows a user to directly access your database
Allows a user to get access to other accounts
Allows a user to read data you don’t want read
Prevention can be as simple as escaping quotes
with mysql_real_escape_string to all user input
$clean_user =
mysql_real_escape_string($_POST[‘username’]);
47. Data Validation
Get what you expect to get
Don’t change it, give error message
Example: (validinsert.php)
Age, should be less than 110, and numeric. Reject
anything else
if(strlen($age)>3){ //error message }
if(!is_int($age)){ //error message }
if($age>110 || $age<18){ //error message }
48. Data Validation
Get the length you expect
<input type=“text” name=“username” maxlength=“8”>
Make sure the username is no longer than 8
if(strlen($username)>8)){ //error message }
