Number of lines

Fred Atkinson

Is there a function that returns the number of lines in a text
file? If so, what is it?

Thanks,

Fred

Returns an array, count() it.

You have to read the file first.

Either put the file contents in an array and count it:

$lines = count($contents = file($file));
// may leave ^^^^^^^^^^^^ this out!
or put it in a string and count all the "\n"s

$lines = substr_count($contents = file_get_contents($file), "\n");
// may leave this out ^^^^^^^^^^^^

Not if it's a Mac ASCII file... ;) Then it's the "\r"s that you need to
count.

If it's a Unix/Linux server:

$lines=trim(`wc --lines < /path/to/file`);
