Question

Please can someone help me out with the expression required for the following:

A $content variable holds a block of HTML and I want to match it against a string that could contain any ID. So I am looking for <p>###GALLERY(ANY NUMBER HERE)###</p>

This is the code I have already that doesn’t work (sorry new to regex):

if (preg_match("<p>###GALLERY[0-9]###</p>", $content))
{
    // Found
}

Any help would be greatly appreciated.

You need to include delimiters in your expression:

if (preg_match("/<p>###GALLERY[0-9]###<\/p>/", $content))

I’m not sure if you need this, but adding a + quantifier after [0-9] will allow for multi-digit numbers:

if (preg_match("/<p>###GALLERY[0-9]+###<\/p>/", $content))
