也發一個產生隨機字串函數

<無詳細內容> /** * 產生隨機數 * * @param int $length 產生字串長度 * @param int $type 字串類型 * @param bool $special 是否使用特殊字元 * @return string 返回產生的隨機字串 * @example random(10, null, true); */ function random($length, $type = NULL, $special = FALSE) { $str = ""; switch ($type) { case 1: $str = "0123456789"; break; case 2: $str = "abcdefghijklmnopqrstuvwxyz"; break; case 3: $str = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; break; case 4: $str = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789"; break; default: $str = "abcdefghijkmnpqrstuvwxyzABCDEFGHJKLMNPQRSTUVWXYZ23456789"; break; } return substr(str_shuffle(($special != FALSE) ? '!@#$%^&*()_+' . $str : $str), 0, $length); } 複製代碼
