Warning: strpos(): Empty delimiter

[carole2]

Hi i copied the function below from notes in the php manual

http://au.php.net/manual/en/function.str-replace.php

function str_replace_count($find,$replace,$subject,$count)
{
   $subjectnew = $subject;
   $nC="";
   $pos = strpos($subject,$find);
   if ($pos !== FALSE)
   {
     while ($pos !== FALSE)
     {
         $nC = $nC + 1;
         $temp = substr($subjectnew,$pos+strlen($find));
         $subjectnew = substr($subjectnew,0,$pos) . $replace . $temp;
         if ($nC >= $count)
         {
           break;
         }
         $pos = strpos($subjectnew,$find);
     } // closes the while loop
   } // closes the if
   return $subjectnew;
}

I get this a warning:
Warning: strpos(): Empty delimiter for the line:
$pos = strpos($subject,$find);

I am using PHP Version 4.3.8.

Please Help! Thanks

Are you sure $subject has a value?

Yes in one senario the subject would be blank. That must be my error.
