Archimedes 0 Report post Posted July 28, 2008 (edited) First off, we need to meet each other. I am Archimedes! xD I chose this name because I have a joy for mathematics and calculators and such. Archimedes is the man who discovered Pi(3.14159). Things you should know before we start Lesson #1. 1.HTML 2.General scripting knowledge or what it actually does. Alright, to the PHP lessons. 1.PHP stands for PHP; Hypertext Preprocessor. 2.PHP is used all around the world to build dynamic web pages and web sites. Basic Syntax 1. All PHP scripts start with the<?php or <? tag. I'd use the <?php tag just to be a little bit more tidy, just my opinion though. 2. To write something in PHP, we use the 'echo' or 'print' statement, like so. <?phpecho "Hello Xisto!";?> Output: Hello Xisto! 3. All PHP statements end with a semicolon(.(In italics in the first code snippet.) Comments 4. To type comments in PHP we use // for one line comments or /* */ to make a comment block, like in this example. Comments DO NOT end with a semicolon. <?php//This is a one lined comment(has no effect on the script, whatsoever)echo "Hello Xisto!";/*Thisis aComment block(has no effect on the script, whatsoever)*/?> Output: Hello Xisto! Variables 5. At school, you use variables to substitute for numbers. Like, 4f + f = d. f=2, therefore 4*2+2=10. d=10. 6. In PHP, variables are 'saved' with the USD sign($). <?php$text = "Hello";$number = 4;echo $text;?> Output: Hello 8. To type 2 variables after each other, you'd separate them with '. " " .', like so. <?php$text = "Hello";$number = 4;echo $text . " " . $number;?> Output: Hello 4 Operators Operator - Name - Ex. - Output + - Addition - x=2. 4 + x - 6 - - Subtraction - x=2. 4 - x - 2 * - Multiplication - x=2. 4 * x - 8 / - Division - x=2. 4 / x - 2 For a list of all operators, click here. That's it for our first lesson, see ya soon!

yordan 10 Report post Posted July 28, 2008 Nice tuto, thanks. Just a stupid question. You say "PHP stands for PHP; Hypertext Preprocessor."How do you make php with Hypertext Preprocessor ? It should sound more like hpp ? Share this post Link to post Share on other sites

yordan 10 Report post Posted July 28, 2008 PHP = PHP: Hypertext Preprocessor https://en.wikipedia.org/wiki/Recursive_acronym Now I see : PHP â PHP: Hypertext Preprocessor (originally "Personal Home Page" tools, officially changed for PHP 3"Personnal Home Pages" is understandable for PHP, it's a nice historical explanation.

hfbvm 0 Report post Posted April 10, 2009 here's the whole document: What You Should Already Know Before you continue you should have a basic understanding of the following: * HTML * Some scripting knowledge If you want to study these subjects first, find the tutorials on our Home page. What is PHP? * PHP stands for PHP: Hypertext Preprocessor * PHP is a server-side scripting language, like ASP * PHP scripts are executed on the server * PHP supports many databases (MySQL, Informix, Oracle, Sybase, Solid, PostgreSQL, Generic ODBC, etc.) * PHP is an open source software * PHP is free to download and use What is a PHP File? * PHP files can contain text, HTML tags and scripts * PHP files are returned to the browser as plain HTML * PHP files have a file extension of ".php", ".php3", or ".phtml" What is MySQL? * MySQL is a database server * MySQL is ideal for both small and large applications * MySQL supports standard SQL * MySQL compiles on a number of platforms * MySQL is free to download and use PHP + MySQL * PHP combined with MySQL are cross-platform (you can develop in Windows and serve on a Unix platform) Why PHP? * PHP runs on different platforms (Windows, Linux, Unix, etc.) * PHP is compatible with almost all servers used today (Apache, IIS, etc.) * PHP is FREE to download from the official PHP resource: http://php.net/ * PHP is easy to learn and runs efficiently on the server side Where to Start? To get access to a web server with PHP support, you can: * Install Apache (or IIS) on your own server, install PHP, and MySQL * Or find a web hosting plan with PHP and MySQL support Basic PHP Syntax A PHP scripting block always starts with <?php and ends with ?>. A PHP scripting block can be placed anywhere in the document. On servers with shorthand support enabled you can start a scripting block with <? and end with ?>. For maximum compatibility, we recommend that you use the standard form (<?php) rather than the shorthand form. <?php ?> A PHP file normally contains HTML tags, just like an HTML file, and some PHP scripting code. Below, we have an example of a simple PHP script which sends the text "Hello World" to the browser: <html> <body> <?php echo "Hello World"; ?> </body> </html> Each code line in PHP must end with a semicolon. The semicolon is a separator and is used to distinguish one set of instructions from another. There are two basic statements to output text with PHP: echo and print. In the example above we have used the echo statement to output the text "Hello World". Note: The file must have the .php extension. If the file has a .html extension, the PHP code will not be executed. Comments in PHP In PHP, we use // to make a single-line comment or /* and */ to make a large comment block. <html> <body> <?php //This is a comment /* This is a comment block */ ?> </body> </html>Basic PHP Syntax A PHP scripting block always starts with <?php and ends with ?>.
