php实现的一个简单hash算法,可以用来加密,不过这个函数过于简单,不能用来解密
function SimpleHash($str){ $n = 0; // The magic happens here: // I just loop trough all letters and add the // ASCII value to a integer variable. for ($c=0; $c < strlen($str); $c++) $n += ord($str[$c]); // After we went trough all letters // we have a number that represents the // content of the string return $n; } //调用方法: $TestString = 'www.jonasjohn.de'; print SimpleHash($TestString); // returns: 1620
