Re: Best way to check for some certain text in a string

Thats what php manual says on the point... // in PHP 4.0b3 and newer: $pos = strpos($mystring, "b"); if ($pos === false) { // note: three equal signs // not found... } // in versions older than 4.0b3: $pos = strpos($mystring, "b"); if (!is_integer($pos)) { // not found... } "Bogdan Stancescu" <mgv@canad.ro> wrote in message news:3D639BB2.9050508@canad.ro... > If you don't need regexps, use strpos.
