Instructions: The urldecode function in PHP does a pretty good job decoding URL's. One shortcoming is with URL's that contain Unicode characters such as %0. This can cause trouble, especially when working with fixed length string.

Just pass the function your URL

Snippet


  1. //Function to decode URL's that contain Unicode characters
  2. function unicode_urldecode($url)
  3. {
  4.   //split the URL into an array
  5.   $url_array = split ("%",$url);
  6.   //Make sure we have an array
  7.   if (is_array($url_array))
  8.   {
  9.     //Loop while the key/value pair of the array
  10.     //match our list items
  11.     while (list ($k,$v) = each ($url_array))
  12.     {
  13.        //use base_convert to convert each character
  14.        $ascii = base_convert ($v,16,10);
  15.        $ret .= chr ($ascii);
  16.     }
  17.  }
  18.  //return the decoded URL
  19.  return ("$ret");
  20. }
