thought you guys may appreciate this function, allows you to pass an array of urls to download and does so simultaneously using non-blocking sockets, then returns the data in an array.



<?php

// function connects to an array of URLS at the same time

// and returns an array of results.



function multiHTTP ($urlArr) {

 $sockets = Array(); // socket array!

 $urlInfo = Array(); // info arr

 $retDone = Array();

 $retData = Array();

 $errno   = Array();

 $errstr  = Array();

 for ($x=0;$x<count($urlArr);$x++) {

  $urlInfo[$x] = parse_url($urlArr[$x]);

  $urlInfo[$x][port] = ($urlInfo[$x][port]) ? $urlInfo[$x][port] : 80;

  $urlInfo[$x][path] = ($urlInfo[$x][path]) ? $urlInfo[$x][path] : "/";

  $sockets[$x] = fsockopen($urlInfo[$x][host], $urlInfo[$x][port],

                           $errno[$x], $errstr[$x], 30);

  socket_set_blocking($sockets[$x],FALSE);

  $query = ($urlInfo[$x][query]) ? "?" . $urlInfo[$x][query] : "";

  fputs($sockets[$x],"GET " . $urlInfo[$x][path] . "$query HTTP/1.0\r\nHost: " .

        $urlInfo[$x][host] . "\r\n\r\n");

 }

 // ok read the data from each one

 $done = false;

 while (!$done) {

  for ($x=0; $x < count($urlArr);$x++) {

   if (!feof($sockets[$x])) {

    if ($retData[$x]) {

     $retData[$x] .= fgets($sockets[$x],128);

    } else {

     $retData[$x] = fgets($sockets[$x],128);

    }

   } else {

    $retDone[$x] = 1;

   }

  }

  $done = (array_sum($retDone) == count($urlArr));

 }

 return $retData;

}
