I wrote the following code and it does NOT seem to work.

$search = array('/<popup[^>]*>/ie');
$replace = array('make_popup(split_tag(\\0))');
preg_replace($search, $replace, $someText);

If I try the following code, then the replacing seems to work (I just try to get a
dummy back reference \\1)

$search = array('/<p(op)up[^>]*>/ie');
$replace = array('make_popup(split_tag(\\1))');
preg_replace($search, $replace, $someText);

What is wrong in the first part? Thanks and cheers,

richard

Why do you need the /e modifier to preg_replace()?

The first snippet will try to evaluate
make_popup(split_tag(<popup parm1="value1" parm2="value2">))
as if it was php code.

Maybe you want to evaluate
make_popup(split_tag('<popup parm1="value1" parm2="value2">'))
// __________________^_______________________________ ______^__
this instead.


The second snippet (which is also wrong!!) will try to evaluate
make_popup(split_tag(op))

which php will convert (with a warning) to
make_popup(split_tag('op'))



So ... turn on all warnings:
<?php error_reporting(E_ALL); ?>

And check the result of preg_replace without the /e modifier first.



Happy Coding :-)
