initialisation of variable in loop

[Pinkerbot]

$delsoegning ='http://www.google.com/search?q='.$urlord.'&num='.$_POST['antal_hits'].'&lr=lang_da&ie=UTF-8&oe=UTF-8';

$fp = fopen ($delsoegning, 'r') ;
while (!feof ($fp))
{
$buf = trim(fgets($fp, 4096));
$pos = strpos($buf,'<p class=g>');
$antal = strpos($buf,'</b> of about <b>');

if($antal !== false)	 
      {  $tal3[1]=0;
         $tal = explode('</b> of about',$buf);
	//'explode' deler en streng med en streng
         $tal2 = explode('<b>',$tal[1]); 
         $tal3 = explode('</b>',$tal2[1]); 
        //$tal3 indeholder antallet af hits
  }
   }
//her slutter tæller


	echo ' <a 

href="http://www.google.com/search?q='.$urlord.'&lr=lang_da&ie=UTF-8&oe=UTF-8"

target="_blank">'.$ordformer[1].'</a> ('.$tal3[0].'); ';

Somehov the post got sent without a question 🙂

the variable $antal stores a number (the number of hits in a google search), and next time the loop is iterated it should be reset to zero. I have tried several solutions, but somehow it doesn't work. If $antal is not instantiated, the program prints the number from the last iteration once again. How do i get it to not do that?
