Which function, copy() or move_upload_file(), is recommended for file handling in PHP?

When handling file uploads in PHP, it is recommended to use the move_uploaded_file() function instead of the copy() function. This is because move_uploaded_file() is specifically designed for handling file uploads and ensures that the file is securely moved to the specified destination. It also performs additional security checks to prevent malicious file uploads.

// Example code snippet using move_uploaded_file() function
$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.';
}
