mysql - Ajax and php to create table -

-

i have following html code in 1 file:

<html> <head> <script> function showuser(str) { if (str == "") {     document.getelementbyid("txthint").innerhtml = "";     return; } else {      if (window.xmlhttprequest) {         // code ie7+, firefox, chrome, opera, safari         xmlhttp = new xmlhttprequest();     } else {         // code ie6, ie5         xmlhttp = new activexobject("microsoft.xmlhttp");     }     xmlhttp.onreadystatechange = function() {         if (xmlhttp.readystate == 4 && xmlhttp.status == 200) {             document.getelementbyid("txthint").innerhtml = xmlhttp.responsetext;         }     }     xmlhttp.open("get","createtable.php?q="+str,true);     xmlhttp.send(); } } </script> </head> <body>  <form> <select name="users" onchange="showuser(this.value)">   <option value="">select person:</option>   <option value="1">equipment 1</option>   <option value="2">equipment 2</option>   <option value="3">equipment 3</option>   <option value="4">equipment 4</option>   </select> </form> <div id="txthint"><b>person info listed here...</b></div> </body> </html>

my createtable.php code:

<?php $q = intval($_get['q']);  $con = mysqli_connect('localhost','root','','results'); if (!$con) { die('could not connect: ' . mysqli_error($con)); } mysqli_select_db($con,"results"); $sql="create table '".$q."'"; $result = mysqli_query($con,$sql); mysqli_close($con); ?>

when chose equipment one, table named 1 not being created. think wrong near create table part in createtable.php. how can fix this?
