[RESOLVED] Preg_match help

kterry

Does anyone know of a good "how to" for PHPs preg_match function? There is much I can do with it, I just don't know how to use it that well. It still confuses me.

My latest with preg_match is to match the <code></code> tags and run any data in between them through the htmlspecialchars function.

Have you checked out the PHP manual's entry on PCRE?

I think preg_match ('@<code>([.\n]*)</code>@',$text,$match); will solve your problem.
if want a reference for regular expressions, go to http://www.regular-expressions.info

I think preg_match ('@<code>([.\n])</code>@',$text,$match); will solve your problem.

I do not think so. In the first place, [man]preg_replace/man is more appropriate. I would suggest something along these lines:

$text = preg_replace('@<code>(.*?)</code>@me',
                     '"<code>" . htmlspecialchars("$1") . "</code>"', $text);

Thanks so much laserlight. You have nailed it again. I will read through that manual some more and see if I can understand it. I just don't understand the patterns and how I'm supposed to use them and when.
