preg_replace with e modifier, how to use class function

[Jochen Daum]

Hi,

I'd like to use something like

preg_replace("...","$this->somefunction('\\1','\\2');", $content);

It says "Cannot find function somefunction()"
I tried some escaping, but didn't work.

Any ideas?

Jochen

Have you tried preg_replace_callback <http://php.net/preg-replace-callback> yet? The user notes contain several examples of calling class methods.

Actually not. I expected that the callback gets the 'match' delivered,
which I expected to be a string, not an array.

Thanks anyway,

With total disregard for any kind of safety measures Jochen Daum
<jo*********@cans.co.nz> leapt forth and uttered:

preg_replace("#...#ies", "\$this->somefunction('\\1','\\2')", $content);

That should work.

I tried that. I don't think so.

Maybe this helps ...
<?php
class XClass {
function somefunction($a, $b) {
echo 'a = ', $a, '; b = ', $b, "\n";
}

function anotherfunction() {
preg_replace('/(.)-(.)/ies', '$this->somefunction(\'\1\', \'\2\')', 'three-four');
}
}

$x = new XClass;
preg_replace('/(.)-(.)/ies', '$x->somefunction(\'\1\', \'\2\')', 'three-four');

$x->anotherfunction();
?>

Output is:
a = e; b = f
a = e; b = f

Well then I think you tried it wrong, as I copied that
implementation from a working example.

Is this inside a method of a class that defines somefunction() as
another of its methods?

Yes. Here is the original source (taken from the invision board code):

$txt = preg_replace( "#\[url\](\S+?)\[/url\]#ie", "\$this->regex_build_url(array('html' => '\\1', 'show' => '\\1'))", $txt );

The 'e' switch after the regex string instructs preg_replace to
evaluate the replacement string as PHP code.
