Are there any specific considerations to keep in mind when using <input type="image"> in PHP forms?

When using <input type="image"> in PHP forms, it's important to remember that the value of the input will be sent as coordinates (x and y) of the click position on the image, rather than a traditional value like with other input types. To handle this in PHP, you can check for the presence of these coordinates in the $_POST superglobal array and process them accordingly. 

if(isset($_POST[&#039;submit_x&#039;]) &amp;&amp; isset($_POST[&#039;submit_y&#039;])) {
    $x = $_POST[&#039;submit_x&#039;];
    $y = $_POST[&#039;submit_y&#039;];
    
    // Process the coordinates as needed
}
