How can I remove the last line of a file using php?

Question

I've tried a lot of potential solutions, but none of them are working for me. The simplest one:

$file = file('list.html');
array_pop($file);

isn't doing anything at all. Am I doing something wrong here? Is it different because it's an html file?

This should works :

<?php 

// load the data and delete the line from the array 
$lines = file('filename.txt'); 
$last = sizeof($lines) - 1 ; 
unset($lines[$last]); 

// write the new data to the file 
$fp = fopen('filename.txt', 'w'); 
fwrite($fp, implode('', $lines)); 
fclose($fp); 

?>
