File Lockin' !

novon

So I'm trying to figure out how to "flock" a .txt file that I read data from for my PHP image gallery, so far unsuccessfuly, and I was wondering if one of you PHP gurus can show me the light...

Here is what I have so far:

  

\\ $dir is provided earlier

  $pic_info_file="image.txt";
  $pic_info=fopen("$dir/$pic_info_file",'r'); 
  flock($pic_info, LOCK_SH); 
  $contents = fread($pic_info, 20); 
  flock($pic_info, LOCK_UN); 
  fclose($pic_info);

 $number_pics = count ($contents);

Then on another page were I include the above code I have:

\\ $image is provided earlier

list($filename,$comment,$link) = explode(";",$contents[$image]);
$filename = trim($filename);
$comment = trim($comment);

This code breaks the page, no error, any ideas? If you need to whole page code let me know.

Thanks
