Preg_Replace?

Recommended Posts

I do not understand it.

Whenever something is going to be replaced it looks like complete crap...

Can someone explain what this means and explain how you deciphered it?

<?php
preg_replace("/(<\/?)(\w+)([^>]*>)/e", 
             "'\\1'.strtoupper('\\2').'\\3'", 
             $html_body);
?> 

That is some random code I found on a tutorial for this.. I cannot read it..

Thanks!

The RegEx converts the html tags to upper case.

for example

<?php
$html_body = "<body><P>Hello World</P></body>";
$html_body = preg_replace("/(<\/?)(\w+)([^>]*>)/e", "'\\1'.strtoupper('\\2').'\\3'", $html_body);
echo $html_body;
?> 

returns

<BODY><P>Hello World</P></BODY>

note that body becomes BODY
