Reading first line of a file

[Anon]

Ive searched and found nothing to help.

How can i open a file, and then print only its first line?

[greg252]

$lines=explode("\r\n",$file);
echo "$lines[0]";

Right?

[crusty_php]

or:
$content_array = file($file);
echo $content_array[0];

With the other, it returned as the name of the file...

But that reads the entire file, where all you need is only one line - it's a waste of resource. It woul be more efficient to open the file using fopen() and read the first line using fgets().
