1. PHP可阅读随机字符串
此代码将创建一个可阅读的字符串,使其更接近词典中的单词,实用且具有密码验证功能。
- /**************
- *@length - length of random string (must be a multiple of 2)
- **************/
- function readable_random_string($length = 6){
- $conso=array("b","c","d","f","g","h","j","k","l",
- "m","n","p","r","s","t","v","w","x","y","z");
- $vocal=array("a","e","i","o","u");
- $password="";
- srand ((double)microtime()*1000000);
- $max = $length/2;
- for($i=1; $i<=$max; $i++)
- {
- $password.=$conso[rand(0,19)];
- $password.=$vocal[rand(0,4)];
- }
- return $password;
- }
2. PHP生成一个随机字符串
如果不需要可阅读的字符串,使用此函数替代,即可创建一个随机字符串,作为用户的随机密码等。
