Web service call timer
<p>I have a PHP script that sends a request to a web service via soap.  I expect to get a response back in just a few seconds, but if I do not receive a response within 30 seconds I need to send another request voiding my first request.</p>

<p>Any suggestions on the best way to handle this timer feature? Should I be looking at PHP's set<code>_time</code>_limit setting? Looking for any insight or general ideas.</p>

<p>Thanks.</p>
