What is the best way to remove a specific line from a list of domains stored in a text file using PHP?

To remove a specific line from a list of domains stored in a text file using PHP, you can read the file into an array, unset the specific line you want to remove, and then write the updated array back to the file. This can be achieved by using file() to read the file into an array, array_splice() to remove the specific line, and file_put_contents() to write the updated array back to the file. 

<?php
$file = 'domains.txt';
$data = file($file);

// Remove line number 3 (index 2)
unset($data[2]);

file_put_contents($file, implode('', $data));
?>
