Regular Expressions - php

This one is from a friend who is converting his .asp expressions into php:

Why doesn't this work with PHP? It works great on ASP.

oRegExp.Global = TRUE
oRegExp.Pattern = "((.|n)*?)"
strInput = oRegExp.replace(strInput, "$1")

I got this to work on PHP but results are flaky and it's not global. It replaces all instances with just one instance.

$strOutput = eregi_replace("((.|n)*)", "\1", $strOutput);

RE: Regular Expressions - php

heh, regular expressions are never "flaky", they either work properly, or don't..

Anyhow :

php Code:

Original - php Code
<? $strOutput = "<i>blah</i> haha <i>blahthree</i>"; $strOutput = eregi_replace("\[i\](([^[])*)\[/i\]", "\1", $strOutput); print($strOutput); ?>

<?
    $strOutput = "blah haha blahthree";
    $strOutput = eregi_replace("\[i\](([^[])*)\[/i\]", "\1", $strOutput); 
    print($strOutput);
?>

Remember that php uses (backslash) as an escape character as does regex, so you need to escape them for php first.. Not so in ASP.

What do you mean, not global?
