2、PHP生成随机字符串
当我们需要生成一个随机名字,临时密码等字符串时可以用到下面的函数:
~~~
function generateRandomString($length = 10) {
$characters = '0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
$randomString = '';
for ($i = 0; $i < $length; $i++) {
$randomString .= $characters[rand(0, strlen($characters) - 1)];
}
return $randomString;
}
~~~
使用方法如下:
~~~
echo generateRandomString(20);
~~~
