How can PHP scripts ensure that uploaded files can be easily managed and deleted later?

To ensure that uploaded files can be easily managed and deleted later, PHP scripts can save the file path or name in a database along with any relevant metadata. This way, the files can be easily retrieved, updated, or deleted based on the database records. 

// Save uploaded file information in a database
$filename = $_FILES['file']['name'];
$file_path = 'uploads/' . $filename;

// Insert file information into database
$query = "INSERT INTO uploaded_files (file_name, file_path) VALUES ('$filename', '$file_path')";
// Execute query using your database connection

// Retrieve file information from database
$query = "SELECT * FROM uploaded_files WHERE file_name = '$filename'";
// Execute query and retrieve file information

// Delete file and database record
$query = "DELETE FROM uploaded_files WHERE file_name = '$filename'";
// Execute query and delete file from server
unlink($file_path);
