- 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;
