I just read some tutorial on regular expressions... I think this might do the trick:

\[\?.+\?\]

I just read it, so I might be wrong :) .

Here it is, use the Explode Function to split the string into an array.

<?php $myString = '[?menu1 type="horizontal" showName="false"?]'; print "<p>string to check: <b>$myString</b></p>";$explodedString = explode('[?', $myString, 2); $firstBit=$explodedString[1];$secondBit = explode('?]', $firstBit, 2);print "<p>Outcome: <b>$secondBit[0]</b></p>";?>

Or in || or in "" :) lol Doesn't really matter. Be carefull with the quotes, if there are any slashes or forward slashes in the expression and it is not enclosed by one of the delimiters, the expression would fail :)So always enclose in "//" or "||" would do fine :)
