PHP: Retrieving lines from the end of a large text file
php
Solution
If you are on a 'nix machine, you should be able to use shell escaping and the tool 'tail'. It's been a while, but something like this:
$lastLines = `tail -n 500`;
notice the use of tick marks, which executes the string in BASH or similar and returns the results.
Problem
I've searched for an answer for quite a while, and haven't found anything that works correctly. I have log files, some reaching `100MB` in size, around `140,000` lines of text. With `PHP`, I am trying to get the last `500` lines of the file. How would I get the `500` lines? With most functions, the file is read into memory, and that isn't a plausible case for this matter. I would preferably stay away from executing system commands.
