server not downloading complete file

[ternto333]

i have a php script that creates a file.  this part works fine - it always writes 100% of the data to this file. the next part of this script is letting the user download that file. when i run it on my localhost, everything is fine and 100% of the file is there. however, when i run it on a different server, for some reason when you download the file, it always gets cut off at 2000000 bytes. so the file that gets downloaded can be much smaller than the original file. is there something i need to change in the php.ini file or any other suggestions? this is my download.php code:

 

$file=$path.$_GET['file'];

header("Content-type: application/force-download");

header("Content-Transfer-Encoding: Binary");

header("Content-length: ".filesize($file));

header("Content-disposition: attachment; filename =\"".basename($file)."\"");

readfile("$file");
