多个PHP cUrl发布到同一页面 [英] Multiple PHP cUrl posts to same page

问题描述

所以要点是，我需要发布XML数据查询到网关页面以接收一个XML响应，O解析以后，可以有从任何地方3-60查询到这个Web服务，我不幸的是必须运行一个简单的现在循环，一次做一个。在响应方面，我只需要响应中的1行（或最多5行），行2是我需要的包含图像数据的第一行。所以我想要能够选择我正在读的行，如果可能的话。

So the gist is that I need to post XML data query to a gateway page to receive a XML response which O parse later, there can be anywhere from 3-60 queries to this web service, I unfortunately have to run a simple loop right now and do them one at a time. On the response side, I will only need 1 (or a max of 5) of the lines in the response, line 2 is the first line that I need containing image data. So I'd like the ability to select which lines I am reading in if at all possible.

我创建了一个简单的读入功能，我说基本for循环，这里是我目前使用的代码，并希望修订。

I created a simple "Read in" function as I said out of a basic for loop, here's the code that I am currently using and would like to revise.

$part1 = 'XML Beginning'; $part2 = XML End';
$posts = array( 0 => 'SC-010052214', 1 => 'SC-000032972', 2 => 'SC-012535460', 3 => 'SC-011257289', 4 => 'SC-010134078' );


 $ch = curl_init();

  curl_setopt($ch, CURLOPT_URL, 'http://example.com/index.php');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER => 1);
  curl_setopt ($ch, CURLOPT_POST, 1);

 $count = count($posts);
 for($i=0;$i<$count;$i++) {

  curl_setopt ($ch, CURLOPT_POSTFIELDS, "payload=$part1{$posts[$i]}$part2");
  $return[] = curl_exec ($ch);

  }
 curl_close ($ch); 

print_r($return);

限制：我不能使用？post = $ data0& post = $ data1& post = $ data3需要更好的解决方案。

Restrictions: I cannot use ?post=$data0&post=$data1&post=$data3 unfortunately, so I need a better solution. Other than that, I'd like to see what kinds of improvements can be made here.

由于快速反应的限制，

<?php
