php custom hash function example, phpash function

The example in this article describes the implementation method of php custom hash function. Share it with everyone for your reference. The specific analysis is as follows:

Here is a demonstration of a simple hash algorithm implemented in PHP, which can be used for encryption. However, this function is too simple and cannot 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;
}

Calling method:

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

I hope this article will be helpful to everyone’s PHP programming design.
