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(32);
