How can PHP developers efficiently manage and overwrite files with the same name during file uploads?

When uploading files in PHP, developers can efficiently manage and overwrite files with the same name by checking if a file with the same name already exists in the upload directory. If a file with the same name exists, it can be overwritten by deleting the existing file before moving the new file into the directory. 

$uploadDirectory = 'uploads/';
$fileName = $_FILES['file']['name'];

if (file_exists($uploadDirectory . $fileName)) {
    unlink($uploadDirectory . $fileName); // Delete existing file
}

move_uploaded_file($_FILES['file']['tmp_name'], $uploadDirectory . $fileName);
