How can PHP be used in conjunction with JavaScript to streamline the file upload process?

To streamline the file upload process using PHP and JavaScript, you can use AJAX to asynchronously send the file to the server without refreshing the page. This allows for a smoother user experience and faster file uploads. 

<?php
if ($_FILES['file']['error'] === UPLOAD_ERR_OK) {
    $tempFile = $_FILES['file']['tmp_name'];
    $uploadDir = 'uploads/';
    $uploadFile = $uploadDir . basename($_FILES['file']['name']);

    if (move_uploaded_file($tempFile, $uploadFile)) {
        echo "File uploaded successfully!";
    } else {
        echo "Error uploading file.";
    }
} else {
    echo "Error: " . $_FILES['file']['error'];
}
?>
