What are the potential limitations of using PHP for live upload progress compared to other technologies like Java or Flash?

One potential limitation of using PHP for live upload progress compared to technologies like Java or Flash is that PHP is not inherently designed for real-time updates. However, this limitation can be overcome by using AJAX requests to periodically check the progress of the upload and update the user interface accordingly. 

// PHP code snippet using AJAX to check upload progress

// Set up AJAX request to check upload progress
function checkUploadProgress() {
    $.ajax({
        url: 'check_upload_progress.php',
        type: 'GET',
        success: function(data) {
            // Update progress bar or display message to user
        },
        complete: function() {
            setTimeout(checkUploadProgress, 1000); // Check progress every 1 second
        }
    });
}

// Call the function to start checking upload progress
checkUploadProgress();
