PHP Basics.

I thought that I could write my 2nd post while I’m here and while I’m installing Apple’s iTunes (ONLY NOW? OMG). So, what is exactly PHP?

PHP -> PHP: Hypertext Processor.
Official Website is http://php.net

And huh…How do we start a PHP Code? Like this?

Code: HTML

 


<scripttype="php">


Me: *dies* Of course not. PHP scripts are written to .php files. They start like:

Code: HTML

 


<?php


and end like this:

Code: HTML

 


?>


Note: <?php can also be replaced with <? (IF YOU HAVE short_open_tag [Or whatever] on at your PHP server) or <% (If you have asp_tags on at your php server)

Now, first script. How do we output something? Or better, show something?

Code: HTML

 


<?php
// we start the naughty php tag.

// and we output.
echo 'Show whatever here but don\'t use single quotes unless you escape them. View next part for more info';
// and we finish.
?>


Simple huh? Comments:
To make PHP comments, you can use

Code:

 

//

for a single line comment, or

Code:

 

/* comment */

. Or just use

Code:

 

#comment

for another kind of simple, one-line comments.

ECHO: This outputs. Remember, if you make ECHO using SINGLE QUOTES (‘) you CANNOT USE IT IN YOUR TEXT OR THE SCRIPT WILL BREAK. But you can escape it with a backslash behind them like:

Code: HTML

 


\' \" \'


For don’t, you can use:

Code: HTML

 


don\'t


So, I think that I will write only until here, and expect more updates to this silly tutorial soon.
