8.3.3 Deleting files with unlink()This is NOT the latest copy of this book; click here for the latest version.
To delete files, simply pass a filename string as the only parameter to unlink(). Note that unlink deals only with files - to delete directories you need rmdir().
<?php
if (unlink($filename)) {
print "Deleted $filename!\n";
} else {
print "Delete of $filename failed!\n";
}
?>
Author's Note: if you have a file opened with fopen(), you need to fclose() it before you call unlink()
