Props to Alex @ thedailywtf.com for today's PHP WTF.

I'm rating this as a WTF because:

1. The function only returns a NULL!
2. It uses references to return values
3. It pretty pointless, especially when you have $_GET
4. It's doesn't really work
5. $argv will always have just one element, unless you're running PHP as a shell script interpreter. Then maybe there would be more than 1 argument.
6. $seperator[0] - WTF?! oh why!?
7. It's just soooooo bad. This function is basically made up of different WTF's.

I hope this isn't used in production somewhere... <?php
/* joins argv into one string and then splits it into logical
elements (html formated)*/

function split_arguments($argv,$argc,&amp;$nr_arg,&amp;$args)
{
       $str="";
       $seperator = "&";
       for ($i=0; $i&lt;$argc; $i++)
       {
               if ($i==0) {
                       $str = sprintf("%s",$argv[$i]);
               } else {
                       $str = sprintf("%s %s",$str,$argv[$i]);
               }
       }
       trim($str);
       for ($i=0; $i&lt;strlen($str); $i++)
       {
               if ($str[$i] == $seperator[0])
               {
                       $nr_arg++;
               } else {
                       $args[$nr_arg] .= $str[$i];
               }
       }
       unset($str);
       for ($i=0; $i&lt;=$nr_arg; $i++)
       {
               $args[$i] = rawurldecode($args[$i]);
       }
       return;
}
