preg trouble

[djedery]

For some reason, i CANNOT get preg to match on a double quote. Here's the code:

$bolMatchedWidths = preg_match_all("/width=(\\'|\\"|)(\d+)(\\'|\\"|)/i", $strContent, $aryMatchedWidths);

As you can see, i'm trying to match on any width tags in an HTML page. The \ are in there to account for the fact that the HTML to be searched is being submitted via a form, so magic quotes are causing the single and double quotes to be escaped. So i account for that.

Anyway, my code catches no quotes (an acceptable case), and single quotes, but NOT double quotes. Any idea why???

Since your pattern is inside a double quoted string its not doing what you expected:

$pat = "/width=(\\'|\\"|)(\d+)(\\'|\\"|)/i";
echo $pat

// Gives:
/width=(\'|\"|)(\d+)(\'|\"|)/i

Yup - that seems to be the trouble. What a pain. The only thing i could think of that would fix it was to concatenate multiple strings together, using different delimiters (single or double quote) for each:

$strPattern = "/<.width=(\\'|".'\\"|)(\d+)'."(\\'|".'\\"|).>/i';

Ugly, but it worked.

Thanks for your help!
