The implementation technique of PHP custom hash function

This article mainly introduces the PHP custom hash function, example analysis of the hash function implementation skills, can achieve a simple encryption function, with a certain reference value, the need for friends can refer to the next

This paper introduces the implementation method of PHP custom hash function. The specific analysis is as follows:

This demonstrates a simple hash algorithm implemented by PHP, which can be used for encryption, but this function is too simple to decrypt

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 had a number that represents the  //content of the string  return $n ;}
 

Call Method:

$TestString = ' www.jb51.net ';p rint simplehash ($TestString); returns:1082
