Read & delete entries in txt file

[Sylvain]

Hello, I'm requesting your help here cause I'm really confused.
I'm looking for deleting entries when an image doesn't load on my links test.

I got all my links in a .txt file like this :
links.txt =

Code: [Select]

<div class="gallery">
 <a href="http://www.website.com/page">
  <img src="http://tc16.easythumbhost.com/image.jpg" onerror="ImgError(this)"/>
 </a>
</div>
#enddiv
the "onerror" code in img src sends an "Image Missing" pic.
What I'd want is to change the "onerror" function to open a php script which deletes all the lines of the div.
This is the script I use to show the links on my page :

PHP Code: [Select]

 $links = "links.txt";
 $fd = fopen ($links, "r");
 $content = fread ($fd,filesize ($links));
 fclose ($fd);
 $delimiter = "#enddiv";
 $splitcontent = explode($delimiter, $content);
 $output = array_slice($splitcontent, 0,100);

 foreach ( $output as $divs )
{
 echo "$divs";
}

I've searched hours and tried lots of codes before posting
Help would be very appreciated. Thanks.
