Your problem is likely with the following line, which reads the *entire*
file into an array:
$fcontents = file($filename);
You're also opening and closing a file handle, but never using it. Use
fread after fopen instead of the "file" function. You'll have to decide on
a byte limit instead of a line limit, though.
