Is it recommended to use PHP for handling file uploads, or should JavaScript be used as well?

When handling file uploads, it is recommended to use PHP for server-side processing and validation, as JavaScript alone cannot handle file uploads securely. PHP provides built-in functions and security measures to handle file uploads effectively. JavaScript can be used for client-side validation and user interface enhancements, but the actual file processing should be done on the server using PHP. 

<?php
if($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $targetDir = "uploads/";
    $targetFile = $targetDir . basename($_FILES['file']['name']);
    
    if(move_uploaded_file($_FILES['file']['tmp_name'], $targetFile)) {
        echo "File uploaded successfully.";
    } else {
        echo "Error uploading file.";
    }
} else {
    echo "Error: " . $_FILES['file']['error'];
}
?>
