Note Submitter: vibemachine@hotmail.com ---- A simple function that generates a random string: function str_makerand ($minlength, $maxlength, $useupper, $usespecial, $usenumbers) { /* Author: Peter Mugane Kionga-Kamau http://mugane.homestake.net Description: string str_makerand(int $minlength, int $maxlength, bool $useupper, bool $usespecial, bool $usenumbers) returns a randomly generated string of length between $minlength and $maxlength inclusively. Notes: - If $useupper is true uppercase characters will be used; if false they will be excluded. - If $usespecial is true special characters will be used; if false they will be excluded. - If $usenumbers is true numerical characters will be used; if false they will be excluded. - If $minlength is equal to $maxlength a string of length $maxlength will be returned. - Not all special characters are included since they could cause parse errors with queries. To use all special characters change the if ($usespecial)... line below to read if ($usespecial)$charset="~!@#$%^&*()_+`-={}|\\]?[\":;'><,./" Modify at will. */ $charset = "abcdefghijklmnopqrstuvwxyz"; if ($useupper) $charset .= "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; if ($usenumbers) $charset .= "0123456789"; if ($usespecial) $charset .= "~@#$%^*()_+-={}|]["; if ($minlength > $maxlength) $length = mt_rand ($maxlength, $minlength); else $length = mt_rand ($minlength, $maxlength); for ($i=0; $i<$length; $i++) $key .= $charset[(mt_rand(0,strlen($charset)))]; return $key; }
