How to convert this wget function to php?

Question

wget -d --header="Content-Type:application/xml" --post-data="$(cat <your xml file>)" http://sample.sample.com/api

How do i use this function in php? I want also to get the response from this function. i have a variable in php the viable is like this

$xml = '<sample>
    <Request target="test">
    </Request>
</sample>'

This is the xml that i want to post.

I tried the following:

$url = 'sample.sample.com/api';;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, "$(cat <".$xml.">)"); // receive server response ...
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo $server_output = curl_exec ($ch);
curl_close ($ch);

But it returned this error:

Parsing XML failed: Start tag expected, '<' not found

There are basic curls examples in the documentation. Read them, try them, and if you run into problems, ask about them here. http://www.php.net/manual/en/curl.examples-basic.php — Tchoupi, Mar 23 '13 at 14:17

You should be able to follow a similar scenario as shown at Sending and Receiving XML using PHP. The second portion of that site (To send XML) uses curl to handle this operation which has similar properties to wget, but utilizing the PHP library rather than a command line binary and parameters. I'll include this snippet from the site for longevity.

<?php
  /*
   * XML Sender/Client.
   */
  // Get our XML. You can declare it here or even load a file.
  $xml_builder = '
                  <?xml version="1.0" encoding="utf-8"?>
                  <Test>
                      <String>I like Bharath.co.uk!</String>
                  </Test>
                 ';
  // We send XML via CURL using POST with a http header of text/xml.
  $ch = curl_init('http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']);
  curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: text/xml'));
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_builder);
  curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 0);
  curl_setopt($ch, CURLOPT_REFERER, 'http://www.bharath..co.uk');
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  $ch_result = curl_exec($ch);
  curl_close($ch);
  // Print CURL result.
  echo $ch_result;
?>

if i use this curl_init('http://' . $_SERVER['SERVER_NAME'] . $_SERVER['REQUEST_URI']); and run the script it just never finishes loading, but if i change it to $ch = curl_init(); it runs but i get nothing in response — Aviv Remona, Mar 23 '13 at 14:37
With curl_init, it will set CURLOPT_URL to the value passed to the function. So for you try, http://sample.sample.com/api — Mark Stanislav, Mar 23 '13 at 14:40

I think so ...

$cmd = "wget -d --header=\"Content-Type:application/xml\" --post-data=\"$(cat <your xml file>)\" http://sample.sample.com/api";
exec($cmd);
$outputfile = "dl.html";
echo file_get_contents($outputfile);

There are more system-efficient ways to do this than shelling out. Curl is the right tool. – Jonathan M Mar 23 '13 at 14:19
