I don't think this is the "only possible way".  I have used an html IMG tag,
then created something like a rollover effect that called a php file for the
image.  It was kind of like a stop light, the light was off until focus came
off of a particular form element, javascript then updated the image href
with a few extra arguments, then the light turned green or red.

You can also use a javascript popup window to call a php script.  I'm sure
there are a few ways to do this too.

Here's the javascript

<input type="text" size="45" name="1_1_email" value="" tabindex=1
onChange='validate_email()'><IMG SRC="./trans.gif" NAME=animation width=10
height=10 align=middle>
<SCRIPT>
function validate_email(){
        document.animation.src = "./image.phtml?email=" +
document.forms[0].elements[1].value ;
        return true;
}
</SCRIPT>

here's the php

<?php
        include("get_connected.func");

         // This script checks for the existence of an image file, and outputs it,
         // if the image is not found than it will output a generic image

        $yes_image = "./green.gif";
        $no_image = "./red.gif";


        header("Content-type: image/gif");

        $mysqlconn = new MySQL_class;
        $mysqlconn->Create($db);

        $select = "SELECT COUNT(item_id) FROM mkt_question_response WHERE item_id =
'".$HTTP_GET_VARS["email"]."' GROUP BY item_id";

        $mysqlconn->Query($select);

        if($mysqlconn->rows > 0){
                readfile($no_image);
        }else{
                readfile($yes_image);
        }
?>

FAIK the only possibility is to redirect to the PHP script. Then
you'll get something like:

window.location.href="myscript.php";
