How to echo a single, specific line from a text file

[cgm225]

How do I echo a single, specific line from a text file?  Let's say, for example, the second line?

 

 

Thank you all in advance!

<?php
$str = file_get_contents('file.txt');
$lines = explode("\n", $str);//Use \r\n Instead of \n if used on Windows
echo $lines[1];//Secont Line
?>
