php 自定生成随机密码函数
/ * 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" //开源代码phpfensi.com // 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 ; }查看更多关于php 自定生成随机密码函数 - php函数的详细内容...
