here the expression again:
>>>$tags = array ("script",
>>> "<!--<!\[CDATA\[",
>>> "\]\]>-->");
>>>foreach ($tags as $currentTag)
>>> if (preg_match ("/^<\/". $currentTag. "/", $content))
>>> // do something
As far as I can see (notice: I'm not a regex-king ;) the regex seems correct
to me. The only thing I'm wondering about is the "/^<" (second last line of
the citation). Together with your expression in the array it results in
preg_match("/<\/<!\[CDATA\[/", ...)
I'm wondering if that (</<![CDATA...) is really what you want to match (and
not only <![CDATA without the trailing </).
If it's not that then I suggest you to do simple example scripts where you
have none-dynamic regex's to test if the expression works (that's the way I
do that stuff - no really because I ever think I'd THIS TIME be able to do
it without, but I haven't thought right till today ;)
lot of luck mastering your expressions
