copied!<p>I once had to solve similar problem: doing multiple requests without cumulating the response times.</p> <p>The solution ended up being a custom-build function which used non-blocking <a href="http://www.php.net/sockets" rel="nofollow noreferrer">sockets</a>. It works something like this:</p> <pre><code>$request_list = array( # address => http request string # '127.0.0.1' => "HTTP/1.1 GET /index.html\nServer: website.com\n\n", '192.169.2.3' => "HTTP/1.1 POST /form.dat\nForm-data: ...", ); foreach($request_list as $addr => $http_request) { # first, create a socket and fire request to every host $socklist[$addr] = socket_create(); socket_set_nonblock($socklist[$addr]); # Make operation asynchronious if (! socket_connect($socklist[$addr], $addr, 80)) trigger_error("Cannot connect to remote address"); # the http header is send to this host socket_send($socklist[$addr], $http_request, strlen($http_request), MSG_EOF); } $results = array(); foreach(array_keys($socklist) as $host_ip) { # Now loop and read every socket until it is exhausted $str = socket_read($socklist[$host_ip], 512, PHP_NORMAL_READ); if ($str != "") # add to previous string $result[$host_ip] .= $str; else # Done reading this socket, close it socket_close($socklist[$host_ip]); } # $results now contains an array with the full response (including http-headers) # of every connected host. </code></pre> <p>It's much faster since thunked reponses are fetched in semi-parallel since socket_read doesn't wait for the response but returns if the socket-buffer isn't full yet.</p> <p>You can wrap this in appropriate OOP interfaces. You <em>will</em> need to create the HTTP-request string yourself, and process the server response of course.</p>
