How can the order of functions in PHP be optimized to ensure immediate display of uploaded images without the need for page reloading?

To ensure immediate display of uploaded images without the need for page reloading in PHP, you can optimize the order of functions by first uploading the image file, then saving it to a directory on the server, and finally displaying the image on the webpage using the appropriate HTML tags. This way, the image will be available for display without the need for the page to reload. 

<?php
if(isset($_FILES['image'])){
    $file_name = $_FILES['image']['name'];
    $file_tmp = $_FILES['image']['tmp_name'];
    $upload_path = 'uploads/' . $file_name;
    
    move_uploaded_file($file_tmp, $upload_path);
    
    echo '<img src="' . $upload_path . '" alt="Uploaded Image">';
}
?>

<form method="post" enctype="multipart/form-data">
    <input type="file" name="image">
    <input type="submit" value="Upload Image">
</form>
