Hello Red Chocolate,

I am giving you this code but actually JS is client side language & PHP is server side language so its not possible to assign client side variable to server side.

I have using Ajax in code so that Ajax will assign that variable in PHP code.

XML

<?php if(isset($_REQUEST['query'])): ?>
<script type="text/javascript" id="runscript">
    function test4 () {
        var x="<?php
            echo $_REQUEST['query'];
            $con=mysql_connect("localhost","root","root");
            mysql_select_db("evrylife");
            $result=mysql_query("call PrcEmployeeInsert('".$_REQUEST['query']."' ,'leeee')");
            //$result=mysql_query("select * from users where id='".$_REQUEST['query']."'");
            if($result)
            {
                $v="inserted";
            }
            echo($v); ?>";
        document.write(x);
    }
</script>
<?php
die;
endif; ?>

<div id="response"></div>
<input type="hidden" id="txtFirstName" value="test" />
<script type="text/javascript">
var test = "<?php echo (isset($_REQUEST['query'])?$_REQUEST['query']:'test2'); ?>";
function login()
{
    var c=document.getElementById("txtFirstName").value;
    var xmlhttp = new XMLHttpRequest();
    xmlhttp.onreadystatechange = function(){
        if(xmlhttp.readyState==4) {
            document.getElementById('response').innerHTML = xmlhttp.responseText;
            eval(document.getElementById('runscript').innerHTML);
            test4();
        }
    }
    xmlhttp.open("GET",'test2.php?query='+c,false);
    xmlhttp.send(null);
}
login();
</script>
