Is it possible to create a PHP file that runs once with no errors and deletes itself?

To delete a file in PHP, use the unlink function. Let's go through an example to see how it works. The first argument of the unlink function is a filename which you want to delete. The unlink function returns either TRUE or FALSE , depending on whether the delete operation was successful.
The unlink() function deletes a file.
It's entirely optional but including it provides the opportunity to slip whitespace into the output by accident. If you do that in a file that you include or require before you try to output headers then you'll break your code.
<?php unlink(__FILE__); ?> If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
