PHP is a scripting language originally created for web development and now used as a general purpose programming language. Key developers include Rasmus Lerdorf, Zeev Suraski, and Andi Gutmans. PHP scripts can be embedded into HTML pages and is commonly used to connect web applications with databases. PHP is open source, has a C-like syntax, and an extensive function library that makes it well suited for web development tasks.

Jean Piaget was a Swiss biologist and psychologist born in 1896 who developed the theory of cognitive development. He identified four stages of mental development: the sensorimotor stage from birth to age 2, the preoperational stage from ages 2 to 7, the concrete operational stage from ages 7 to 11, and the formal operational stage from ages 11 to adulthood. Piaget passed away in 1980 and made significant contributions to understanding how children's understanding of the world develops through these stages.

AJW tells the story of needing tape and visiting the three little pigs' houses. At the first two houses, AJW sneezes and finds the pigs dead, eating them. At the third house, the pig is rude but accepts AJW's invitation to tea, where AJW gets the needed tape.

The document discusses a car park barrier that provides a flexible solution to avoid unnecessary damage from vehicles. It can protect walls, building supports, machinery, and equipment from wayward vehicles. The barrier is made of modular components and has high impact absorption properties to ensure vehicles hitting it suffer little to no damage. It can be used to define and segregate car park areas and comply with regulations.
El documento describe la experiencia de viaje a Italia de un estudiante para participar en el programa Comenius. Fue recibido cálidamente por su familia anfitriona y compañeros de estudio, y pudo aprender sobre la cultura italiana a través de visitas turísticas y probar la comida típica. El estudiante disfrutó especialmente del tiempo pasado con su amiga Sara, su correspondiente en el programa, y se sintió como en casa gracias a la hospitalidad de su familia durante la estancia.
Este documento compara dos obras pictóricas de los artistas impresionistas Pierre-Auguste Renoir y Edgar Degas. Describe el movimiento impresionista y sus características, así como las biografías y estilos de los dos artistas. Analiza sus obras "Los paraguas" de Renoir y "Clase de danza" de Degas, contrastando sus enfoques iconográficos y formales.

2. PHP Origins
Rasmus Lerdorf (born Greenland, ed Canada)
PHP originally abbreviation for ‘Personal Home Pages’,
now ‘PHP Hypertext Processor’
Other key developers: Zeev Surashi and Andi Gutmans
(Israel)
Open Source
PHP version 4.4.3 current at UWE
Due to upgrade to PHP 5
3. Scripting languages
• A scripting language is:
– often evolved not designed
– cross-platform since interpreter is easy to port
– designed to support a specific task – PHP -> Web support
– un-typed variables (but values are typed)
– implicit variable declaration
– implicit type conversion
– stored only as script files
– compiled on demand
– may run on the server (PHP) or the client (Javascript)
• What design and development are involved in using a
scripting language like PHP for development in place of
a compiled language (Java in JSP, .NET)?
4. PHP details
• Procedural language
– Compare with Javascript which is event-driven
• C-like syntax - { } ;
• Extensive Function Library
• Good Web-server integration
– Script embedded in HTML
– Easy access to form data and output of HTML pages
• Not fully object-oriented
– Java is fully object oriented – all functions have to be
in a class
– In PHP, classes are additional but quite simple to use
5. PHP and HTML
• HTML-embedded
– PHP scripts are essentially HTML pages with
the occasional section of PHP script.
– PHP script is enclosed in the tag pair:
• <?php print date(“H:I”) ?>
6. C-like language
• Free format - white space is ignored
• Statements are terminated by semi-colon ;
• Statements grouped by { … }
• Comments begin with // or a set of comments /* */
• Assignment is ‘=’: $a=6
• Relational operators are ,< , > == ( not a single equal)
• Control structures include if (cond) {..} else { }, while (cond) { .. } ,
for(sstartcond; increment; endcond) { }
• Arrays are accessed with [ ] : $x[4] is the 5th element of the array
$x – indexes start at 0
• Associative Arrays (hash array in Perl, dictionary in Java) are
accessed in the same way: $y[“fred”]
• Functions are called with the name followed by arguments in a fixed
order enclosed in ( ) : substr(“fred”,0,2)
• Case sensitive - $fred is a different variable to $FRED
7. Function library
• Basic tasks
– String Handling
– Mathematics – random numbers, trig functions..
– Regular Expressions
– Date and time handling
– File Input and Output
• And more specific functions for-
– Database interaction –
• MySQL, Oracle, Postgres, Sybase, MSSQL ..
– Encryption
– Text translation
– Spell-checking
– Image creation
– XML
8. String Handling
• String literals (constants) enclosed in double quotes “ ”
or single quotes ‘ ’
• Within “”, variables are replaced by their value: – called
variable interpolation. “My name is $name, I think”
• Within single quoted strings, interpolation doesn’t occur
• Strings are concatenated (joined end to end) with the
dot operator “key”.”board” == “keyboard”
• Standard functions exist: strlen(), substr() etc
• Values of other types can be easily converted to and
from strings – numbers implicitly converted to strings in a
string context.
• Regular expressions be used for complex pattern
matching.

10. Learning PHP
• Start with just the basics, installing a script
to output an HTML page
• Understand how PHP supports interaction
with the Browser or other clients
• Understand how PHP supports integration
with databases – MySQL
• Understand how PHP supports integration
with other applications – Web services
