preg_match() question: Operation to occurrence does not result

[thenetflyer]

<?php

/*
Using a function to perform an operation to an occurrence before
returning it to the replacement string does not work in preg_replace.
Consider the following code in which I want to urlencode the
replacement string which does not work.
I tried to call another function but that did not work either.

May be I do something wrong ???

Thanks,

Klaas

$string = "<a href=\"/path/path2/script.php?sess ion_id=zEFCFClD mmlFFHE15416&op tion=myoption\" >My
Option</a><br>";

echo "urlencode the parameter part: [" .
preg_replace('/(<a.+href=\")([^\"]+)/i', "$1". urlencode('\\2' ),
$string) . "]\n";
echo "uppercase the parameter part: [" .
preg_replace('/(<a.+href=\")([^\"]+)/i', "$1". strtoupper("$2" ),
$string) . "]\n";

You need to specify the /e option in the regular expression
