How can PHP be used to detect active file uploads and prevent data loss during the upload process?

To detect active file uploads and prevent data loss during the upload process, you can use PHP to check for the presence of uploaded files in the temporary directory and handle them accordingly. By monitoring the upload progress and ensuring that the file is successfully moved to its intended destination, you can prevent data loss in case of interruptions during the upload process. 

if(isset($_FILES['file']['tmp_name']) && is_uploaded_file($_FILES['file']['tmp_name'])) {
    $tempFile = $_FILES['file']['tmp_name'];
    $targetFile = 'uploads/' . $_FILES['file']['name'];
    
    if(move_uploaded_file($tempFile, $targetFile)) {
        echo 'File uploaded successfully!';
    } else {
        echo 'Error uploading file.';
    }
} else {
    echo 'No file uploaded.';
}
