Question

I need retrieve data from 2 tables at the same time, the tables are not linked by foreigns keys or such.

$query1 = "select idemployee from employee where address like 'Park Avenue, 23421'";
$query2   "select idcompany from company where bossName  like 'Peter'";

How can I do this with a kinda thread in PHP?. I’ve heard that threads are no safe in PHP.

UPDATED:

I got an input field that needs to looks data in both tables, is like search on both tables and show the posible results based on the employee address or boss’s name, so you can type an address or just the boss’s name. It’s just a representation on what I need

Answer 1

Depends on what do you want to do with those queries. If, for example, you are using an AJAX form and can make two requests, you should create separate scripts, where each returns the results for each query. That is effectively running them in separate processes, so they execute simultaneously.

There is no such thing as threading per se in PHP, you can see a hack around it here (using full fledged processes.)
