What are the benefits of using functions like copy() or move_uploaded_file() for handling file uploads in PHP?

When handling file uploads in PHP, using functions like copy() or move_uploaded_file() is beneficial because they provide a secure way to move uploaded files from the temporary directory to a specified destination. These functions help prevent security vulnerabilities such as directory traversal attacks and ensure that only valid files are moved to the desired location. Additionally, they simplify the process of handling file uploads by abstracting away the manual file handling tasks.

<?php
$uploadedFile = $_FILES['file']['tmp_name'];
$destination = 'uploads/' . $_FILES['file']['name'];

if (move_uploaded_file($uploadedFile, $destination)) {
    echo "File uploaded successfully.";
} else {
    echo "Error uploading file.";
}
?>
