How do I open a file from line X to line Y in PHP?

Question

The closest I\'ve seen in the PHP docs, is to fread() a given length, but that doesnt specify which line to start from. Any other suggestions?

Unfortunately, in order to be able to read from line x to line y, you'd need to be able to detect line breaks... and you'd have to scan through the whole file. However, assuming you're not asking about this for performance reasons, you can get lines x to y with the following:

$x = 10; //inclusive start line
$y = 20; //inclusive end line
$lines = file('myfile.txt');
$my_important_lines = array_slice($lines, $x, $y);
