產生密碼 Generated passwords

 <?php

 echo get_rand_password(4); //密碼長度可以使用數字控制 
 
function get_rand_password($len = 8) //Password length can use digital control
{
    // remove o,0,1,l
    $word[] = 'abcdefghijkmnpqrstuvwxyz';
    $word[] = 'ABCDEFGHIJKLMNPQRSTUVWXYZ';
    $word[] = '!@#$%^&*+-=';
    $word[] = '23456789';
  
    $word_str = '';
    foreach($word as $v)
        $word_str .= $v;
  
    $password ='';
    $l = strlen($word_str);
    for ($i = 0; $i < $len; $i++) {
        $password .= $word_str[rand() % $l];
    }
