<?php
$lines = file(lines.txt);
echo $lines[sizeof($lines)-1];
?>

or

<?php
$lines = file(lines.txt);
echo $lines[sizeof($lines)];
?>

depending on whether your text file has a trailing cr/lf.

<?
	
   $foo = file("contact.html");
   $lastline = count($foo) - 1;
   echo "Lastline $lastline : " . $foo[$lastline]  . "<br>\n";

?>

could be combined as

<?php
$lines = file("lines.txt"); //you forgot the quotes here :)
$sf = sizeof($lines);
echo (empty(trim($lines[$sf])) ? $lines[$sf - 1] : $lines[$sf]);
?>

making it not matter anymore whether the file has a cr/lf at the end or not.
(note, only having whitespace characters on the last line, which should be
echoed instead of ignored, will be heavily screwed up by this)
