$file_array = file($file_name);

foreach ($file_array as $line_number =$line)
{
// Handle the line
}

The problem with your solution is it reads the entire file into the
array. Note he said LARGE FILE. This could very quickly run him out of
memory.

Ikciu has the correct answer. fgets() is the way to go.

What if the file is larger than memory_limit (8Mb)?

fgets() is the right answer in this case.

So, instead of coding with file() which works now with a 200K file,
start with fgets and your script will not break when the file grows.

I would go fgets, this will allow you to control how much of the file
you would like to do, or maybe possibly do it in batches.
