使用php将android连接到mysql数据库：多用户支持？

Question

I am trying to develop an android application. In the application the user can search some data from the database that is on the server side. For that, I use a php script that is on the server side along with mysql database. I give it a call from the android app and the php code connects with the database and returns a json result which I decode and use it as I want.

My question is this. Can this support multiple users at the same time? For example 2 different users use at the same time the search function for retrieving data from the database. I know that the database itself can handle this kind of requests, but what about the php service?

Here is an example of the php code:

<?php
     mysql_connect("host","username","password");
     mysql_select_db("Deal");
     $sql=mysql_query("select * from CITY where CITY_NAME like 'A%'");

     while($row=mysql_fetch_assoc($sql))
       $output[]=$row;

     print(json_encode($output));
     mysql_close();
?>

PHP script is being launched by web-server environment. It's hard to imagine there exists web-server that doesn't support multi-threading at present. So, don't worry. The answer is positive.
