here's how you could empty the contents of TestNewIPs.txt file using PHP:

<?php

// Open the input file for writing (this will truncate its contents)
$inFile = fopen('TestNewIPs.txt', 'w');

// Close the input file
fclose($inFile);

?>

This PHP code will open TestNewIPs.txt file for writing, which will truncate (empty) its contents. Then, it will close the file handle to release any resources used by the file. Note that this code will erase the contents of the file, so make sure you have backed up any important data before running it.
