This is an example of appending to file. In PHP, we can delete any file using unlink() function.
The unlink() function accepts one argument only: file name.
bool unlink ( string $filename [, resource $context ] ) $filename represents the name of the file to be deleted.
Lets put this into example.
<?php
$status=unlink('file2.txt');
if($status){
echo "File deleted successfully.";
}else{
echo " File not deleted.";
}
?>
