Php custom hash function instance and phphash function. Php custom hash function example. phphash function this article describes the php custom hash function implementation method. Share it with you for your reference. The specific analysis is as follows: the php user-defined hash function instance implemented by php and the phphash function are demonstrated here.

This example describes how to implement the php custom hash function. Share it with you for your reference. The specific analysis is as follows:

A simple hash algorithm implemented by php can be used for encryption. However, this function is too simple to be used for decryption.

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;}

Call method:

$TestString = 'www.jb51.net';print SimpleHash($TestString); // returns: 1082
