php 自定生成随机密码函数
<?php //原来是Zend.com,由亨特reproducted /* 用法:$ new_password = return_password(); 示例:生成密码:2X5bjj2z,ERgid62Y,p2sHtDPv */ 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 //排除一些特殊字符和字母数字混淆 // 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; }
