Take alook at the second example at http://uk.php.net/manual/en/function.preg-replace.php

The 1st parameter is what the function will look for in the defined string, the 2nd parameter is what will be replaced if there are matches in the string, and the 3rd parameter is the string you define.

I,e

PHP Code:


		
			
<?php



    // my string that i am making

    $string = "assassingod is the best at everything";



    // what its looking for and if theres a match itll be replaced

    $patterns[0] = "/best/";

    $patterns[1] = "/at everything/";



    // what is going to be inplace of what has been removed

    $replacements[0] = "worst";

    $replacements[1] = ".";



    echo preg_replace($patterns, $replacements, $string);

    

?>

The output of that will be

Quote:

assassingod is the worst .

(Of course that's a false statement;))

Ok, thanks for that assassingod..

What about 3 and 4 and 5..

PHP Code:


		
			
"/(<\/?)(\w+)([^>]*>)/e", 

             "'\\1'.strtoupper('\\2').'\\3'"

Like what is all that...that is what confuses me :D

Those are regular expression pattern matchers. They were taken from perl. As much as I I'd like to sit down an explain to you about them I don't know much about them myself yet ;) In fact it would take anyone some time to explain it. I suggest looking for some tutorials on 'PHP regular expressions' and reading the section in the PHP manual about them. They're quite hard to get your head around :)
