Note Submitter: anonymous at vitut dot us ---- in_array is pretty slow on big arrays, I used isset() instead in one of my projects. It works well if you are building the array yourself. old way... // build some array while (something) $array[] = $value; // use it to check something if (in_array($search, $array)) { // something... } better way... // build some array while (something) $array[$value] = true; // use it to check something if (isset($array[$search])) { // something... } if you are using something like this, the improvement in speed is immense when using isset() instead of in_array()
