php 自定產生隨機密碼函數

<?
/ /原來是Zend.com，由亨特reproducted

用法：$ new_password = return_password（）;
樣本：產生密碼：2X5bjj2z，ERgid62Y，p2sHtDPv

代碼如下

function return_password () { // set password length $pw_length = 8; // set ASCII range for random character generation $low_ascii_bound = 50; // "2" $upper_ascii_bound = 122; // "z" // Exclude special characters and some confusing alphanumerics 排除一些特殊字元和字母數字混淆 // o,O,0,I,1,l etc $notuse = array (58,59,60,61,62,63,64,73,79,91,92,93,94,95,96,108,111); while ($i < $pw_length) { mt_srand ((double)microtime() * 1000000); // random limits within ASCII table $randnum = mt_rand ($low_ascii_bound, $top_ascii_bound); if (!in_array ($randnum, $notuse)) { $password = $password . chr($randnum); $i++; } } return $password; }
