What issue is the user facing when trying to delete files in PHP?

The user is likely facing a permission issue when trying to delete files in PHP. To solve this problem, the user needs to ensure that the PHP script has the necessary permissions to delete files in the specified directory. This can be achieved by setting the correct file permissions or running the PHP script as a user with the appropriate permissions. 

<?php
$filename = 'example.txt';

// Check if the file exists
if (file_exists($filename)) {
    // Check if the PHP script has permission to delete the file
    if (is_writable($filename)) {
        // Delete the file
        unlink($filename);
        echo 'File deleted successfully.';
    } else {
        echo 'Permission denied to delete the file.';
    }
} else {
    echo 'File does not exist.';
}
?>
