How to delete a file if exists in PHP?

First, define a vari
able that stores the path to the directory in which you want to delete files.

Second, use the glob() function to search for all files in the directory $dir that has the *.tmp extension and pass it result to the array_map() function to delete the files.


$dir = 'temp/';
array_map('unlink', glob("{$dir}*.tmp"));

The following example uses the unlink() function to delete the readme.txt file:


$filename = 'readme.txt';

if (unlink($filename)) {
	echo 'The file ' . $filename . ' was deleted successfully!';
} else {
	echo 'There was a error deleting the file ' . $filename;
