How can PHP developers differentiate between multiple submit image buttons within a single form without using hidden fields?

To differentiate between multiple submit image buttons within a single form without using hidden fields, PHP developers can utilize the name attribute of the submit buttons. By giving each submit button a unique name, developers can identify which button was clicked when the form is submitted. This can be achieved by checking the value of the submitted button in the PHP code to determine the action to take based on which button was clicked. 

<form method="post" action="form_handler.php">
    <input type="image" src="button1.png" name="button1" />
    <input type="image" src="button2.png" name="button2" />
</form>

<?php
if ($_SERVER["REQUEST_METHOD"] == "POST") {
    if (isset($_POST['button1'])) {
        // Code to handle button1 submission
    } elseif (isset($_POST['button2'])) {
        // Code to handle button2 submission
    }
}
?>
