Loading php via <script language="javascript"...>

    I'm building a small tracking script for some of my domains and want to load a php script from another domain. I just need to gather the ip address of the visitor on domain A and pass it to another script on domain B.

    There is no way to get the ip address with pure javascript so I thought I go for a mix of php and javascript which seems to work like in this case.
    http://www.hashemian.com/tools/visitor-IP.htm

    <script language="JavaScript" src="http://scripts.hashemian.com/js/visitorIPHOST.js.php"></script>
    Code (markup):
    He uses this snippet to embed a fake javascript file and then uses probably $_SERVER['RemoteADDR'] to get the ip and parses it back to the site.

    My problem is that I can't get parse any output on domain A that has the script from domain B embedded.

    I tried to echo the results or document.write but nothing worked. It is displayed if I view the file on domain B but not if I embed it on domain A.


    Any help would be great. If you have other suggestions how I could gather the ip on domain A and pass it on to the script on domain B would be cool too.

    How about something like this. On Domain A (http://testDomainA.com) make your ip fetching script, we'll call it get_ip.php:

    function getRemoteIp() {
	var toReturn='<?= getenv('REMOTE_ADDR') ?>';
	return toReturn;
}
    Code (markup):
    And on Domain B you can call the getRemoteIp() javascript function.. like for example to fill in a form element or something:

    <html>
<script language="JavaScript" src="http://testDomainA.com/get_ip.php"></script>
<script language=JavaScript>
function showIp() {
        var foundIp=getRemoteIp();
        document.getElementById('ipField').value=foundIp;
}
</script>
<body onLoad='showIp();'>
This is a test.<p>
Your Ip is: <input type=text size=25 value='' id='ipField'>
</body>
</html>
