Note Submitter: webdesign at innato dot nl ---- It took me a while to discover that you must escape characters like parentheses (), square brackets [] and ^ (and maybe more) if you want to match these as a literal. Otherwise you may get some erratic outcome. In summary, using a match anywhere in the string as an example: <?php $needle = "["; $haystack = "some_array[]"; $test= mb_ereg_match(".*".$needle, $haystack); // returns false and a php warning $test= mb_ereg_match('.*'.preg_quote($needle), $haystack); // returns true ?>
