[PHP] Reading Text file by line

[Anthony]

I need to read a text file by line, if I open the file and use fgets() then
it doesn't pick up the EOL corretly.  So I was planning on reading the whole
file in with fread() and then breaking it up by EOL characters.  My question
is, how do I do it?  What character do I search for in the string?  Anyone
have a simple example on how to do this?  Thanks.

Using 

$var=file('filename.txt');

Creates an array, with each element in the array being 1 line of the file.

Thanks

A line is usually terminated by either LF (Unix-Style) or CRLF (Win
style). I heard that some macies do it the other way round, terminating
with either only CR ot LFCR.

If you don't know exactly how lines will be terminated, first use
str_replace to normalize the line terminations:

$data = str_replace(array(\r\n, \n\r, \r, \n), \n, $data);

then simple explode() the data to receive an array of lines:

$arlines = explode(\n, $data);

You could also use preg_split to combine these operations:

$arlines = preg_split(/(\r\n|\n\r|\r|\n)/s, $data);
