In PHP 4.1.2 (and 4.2.0-dev) Calling file() on a 4-line 
text file with Macintosh line endings (CR) results in a 
1-element array:

file: (file.txt)

blah
test
three
four

Code:

$array = file( 'file.txt. );
echo count( $array );

>> Returns '1' (Verified by print_r)

file() is ignoring the line endings, but the correct result 
happens for files with Windows (CRLF) and Unix (LF) line 
endings.

This seems critical as this is such a commonly used function.  (and Derick promised it would be fixed by 4.3.0 :)
 [2002-09-23 13:36 UTC] wez@php.net 
Fixed in HEAD.
Please try a non-stable snapshot and set the new ini option
auto_detect_line_endings=on in your php.ini/apache.conf.
The fix will be in 4.3.

--Wez.

is there a work around for this? just some way to go 
through the array containing the file, line by line.

Im using PHP 4.2.2

If you must use PHP < 4.3, you can do something like this:

$fp = fopen($filename, "r");
$data = fread($fp, filesize($filename));
fclose($fp);
$lines = explode("\r", $data);

BEWARE: file() keeps the \r at the end of each line,
whereas the code snippet above does not.
