Send multiple xml requests in parallel in PHP? Possible?
<p>I have a script that makes calls to an XML api on a remote server.  Currently my script sends 10 requests serially to the remote server.  It fully processes each request before sending the next one.  This is a huge bottleneck for my server at the moment since each API request can take up to a second each.  Since most of the time is spent waiting for the remote server to respond, I'm wondering if/how I can send the requests in parallel so that all 10 requests use the same one second latency instead of ten one second latencies...</p>

<p>I thought about calling the script 10 times using a system command and running them in the background to effectively create 10 processes, but I'm not sure if that's the best way to do it.  I figure this problem has probably been solved before.</p>
