How can you check if an image button was clicked in PHP?

To check if an image button was clicked in PHP, you can use the isset() function to determine if the button's name or value is present in the $_POST or $_GET superglobals. This allows you to detect if the button was clicked and trigger the desired action accordingly. 

```php
if(isset($_POST['image_button_name'])){
    // Image button was clicked, perform desired actions here
    // For example, redirect to another page or execute a function
}
```

In this code snippet, replace 'image_button_name' with the actual name or value of the image button you want to check. This code should be placed in the PHP file that processes the form submission containing the image button.
