function getTextDelims($alltext, $opener, $closer)
{
preg_match_all('/'.preg_quote($opener).'(.+)'.preg_quote($closer).'/mU', $alltext, $allmatches);
if ((count($allmatches) > 0) and (array_key_exists(1, $allmatches)))
{ return $allamtches[1]; }
else { return array(); }
}
Then doing
$myanswers = getTextDelims(.....
$myanswers[1] contains offset 1, etc
If you want to make the matches case-insensitive, change '/mU' to '/mUi'
