My javascript file:
var ms = 3000;
$.get("curl.php", { test: ms } );
My curl.php:
$ms = $_GET("test");
echo $ms;
Firefox firebug says:
Fatal error: Function name must be a string in C:\Users\Jansu\Documents\workspace\php\curl.php on line 2
what could be the problem?
Even better would be when the javascript and php code is in the same file, so I don't have to post/get anything. Just somehow pass javascript to php.
You want [], not () (docs):
$ms = $_GET["test"];
Re your edit:

Even if they're in the same file, they're executed in completely different places. The JavaScript is executed on the client, the PHP is executed on the server. To get data from the client to the server, it has to be sent there. Ajax (the way you did it) is the primary way you do that without causing a full page refresh, so you're on the right track.
curl.php resource, the PHP code within it gets run. You can use logic within your PHP code to only run the relevant bits, or (probably better) have a separate PHP file for processing the ajax request, since it's best to keep distinct things separated.You don't mention if you are sanitising your data separately, but the filter_input function is more secure than calling $_GET directly.
Also POST is generally considered better than GET for AJAX calls as it doesn't have the same string length limit, slightly more secure too.
$ms = filter_input(INPUT_POST, 'test', FILTER_SANITIZE_STRING);
<script type="text/javascript">
var ms = 9000;
function test()
{
$.ajax({ url: "a.php",
data: {"test":ms},
type: 'get',
success: function(output) {
$('#testing').html(output);
}
});
}
test();
</script>
<?php
$ms = $_GET["test"];
echo "$ms";
?>
<div id="testing">
</div>
You can echo the output in any HTML element. Here i'm using div.
