preg_replace...er, What it Do?

[Digital Jedi]

Assuming I wanted to replace a large portion of the navbar template with a custom template, let's say from [minicode]<!-- nav buttons bar -->[/minicode] to [minicode]<!-- / nav buttons bar -->[/minicode], would the first part of this plugin be correct?

PHP Code:

$template = $vbulletin->templatecache['navbar'];
$match = '<!-- nav buttons bar/.+/nav buttons bar -->';
$replace = $vbulletin->templatecache['djs_navbar']; 


This is assuming that dot matches newlines. What I don't know what to do know, is what to do with the [minicode]preg_replace[/minicode] function itself. I thought something like:

PHP Code:

$vbulletin->templatecache['navbar'] = preg_replace($match, $replace, $template); 


But until I've got the first part right, I'm just guessing. Not to mention, I have no idea which hook will work in this case.
