why is my description limiter not working ?

PHP Code:


		
			
<?php



//only use when needed!

//ini_set("user_agent","Internet Explorer");



//Edit here for your rss link

$location = "http://youtube.com/rss/global/top_rated.rss";



$contents = file_get_contents($location);

$xml        = new SimpleXMLElement($contents);

$limiter = 0;

$deslimit = $item->description = 0;



print "<ol>";



foreach($xml->channel->item as $item) {

    print "<li>";

print "<a href='".$item->link."' title='".$item->title."'>";

print $item->title;

print "</a>";

print "<p>".$item->description."</p>";

print "</li>";

$limiter++;

if ($limiter == 5) break;

$deslimit++;

if ($deslimit == 100) break;



}



print "</ol>";







?>

With Noia from #talkPHP:

PHP Code:


		
			


<?php 



//only use when needed! 

//ini_set("user_agent","Internet Explorer"); 



//Edit here for your rss link 

$location = "http://youtube.com/rss/global/top_rated.rss"; 



$contents = file_get_contents($location); 

$xml        = new SimpleXMLElement($contents); 

$deslimit = 100;



print "<ol>"; 



// Loop results

foreach($xml->channel->item as $item) { 

    

    print "<li>"; 

    

    print "<a href='".$item->link."' title='".$item->title."'>"; 

    print $item->title; 

    print "</a>"; 

    

    // Edit description to length

    if(strlen($item->description) > $deslimit) {

        $item->description = trim(substr($item->description), 0, $deslimit) . '...';        

    }

    

    print "<p>".$item->description."</p>"; 

    print "</li>"; 



} 



print "</ol>";

Not tested, but should work :)
