Sending and Recieving XML via cURL

I'm new to sending, receiving, and reading XML. I'm trying to send and receive XML data via cURL. I am using curl because it was so easy with just arrays. I am using the following code to generate the XML and the PHP script that is presently not working. It would be great if some great code god can explain whats wrong to me.

build_xml.php

<?php
'<?xml version="1.0"?>'
$xml = "<member><name>name</name></member>";
echo $xml;
?>

Code (markup):

Array Method - Works great with arrays. I tried with XML as $data, and it no work. Getting it working this way is preferred.

<?php
exec("/usr/bin/curl -m 120 -d \"$xml\" http://www.example.com/index.php -L", $response);
// $response is null
?>

Code (markup):

Alternate Method - This way is failing also.

<?php 
$url = "build_xml.php";
$ch = curl_init();    // initialize curl handle
curl_setopt($ch, CURLOPT_URL,$url); // set url to post to
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); // return into a variable
curl_setopt($ch, CURLOPT_TIMEOUT, 4); // times out after 4s
curl_setopt($ch, CURLOPT_POSTFIELDS, $XPost); // add POST fields
$result = curl_exec($ch); // run the whole process
echo $result; //contains response from server 
// NO RESPONSE RECEIVED
?>

Code (markup):

 

<?php
	/** 
	 * Define POST URL and also payload
	 */
	define('XML_PAYLOAD', '<?xml version="1.0"?><member><name>name</name></member>');
	define('XML_POST_URL', 'http://www.domain.com/build_xml.php');
		
	/**
	 * Initialize handle and set options
	 */
	$ch = curl_init(); 
	curl_setopt($ch, CURLOPT_URL, XML_POST_URL); 
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	curl_setopt($ch, CURLOPT_TIMEOUT, 4); 
	curl_setopt($ch, CURLOPT_POSTFIELDS, XML_PAYLOAD); 
	curl_setopt($ch, CURLOPT_HTTPHEADER, array('Connection: close'));
	
	/**
	 * Execute the request and also time the transaction
	 */
	$start = array_sum(explode(' ', microtime()));
	$result = curl_exec($ch); 
	$stop = array_sum(explode(' ', microtime()));
	$totalTime = $stop - $start;
	
	/**
	 * Check for errors
	 */
	if ( curl_errno($ch) ) {
		$result = 'ERROR -> ' . curl_errno($ch) . ': ' . curl_error($ch);
	} else {
		$returnCode = (int)curl_getinfo($ch, CURLINFO_HTTP_CODE);
		switch($returnCode){
			case 404:
				$result = 'ERROR -> 404 Not Found';
				break;
			default:
				break;
		}
	}
	
	/**
	 * Close the handle
	 */
	curl_close($ch);
	
	/**
	 * Output the results and time
	 */
	echo 'Total time for request: ' . $totalTime . "\n";
	echo $result;  	
	
	/**
	 * Exit the script
	 */
	exit(0);
?>

PHP:

 

Note: the error checking section should actually look something like this:

	/**
	 * Check for errors
	 */
	if ( curl_errno($ch) ) {
		$result = 'cURL ERROR -> ' . curl_errno($ch) . ': ' . curl_error($ch);
	} else {
		$returnCode = (int)curl_getinfo($ch, CURLINFO_HTTP_CODE);
		switch($returnCode){
			case 200:
				break;
			default:
				$result = 'HTTP ERROR -> ' . $returnCode;
				break;
		}
	}

PHP:

Notice the difference is in the switch so it captures the non-200 response code.

Thanks bobbie. I'm trying now.

 

wow it works great. thanks so much.

i did notice that it only accepts one reply value. can it receive an xml data set like its sending?

otherwise its perfect. great solution.

 

I've tried using this solution and the xml comes over as an array. Is that what we should be expecting. As I'm sending to a third party its hard to know if the issue may be on their end.

(I'm hoping someone is still getting replies to this thread.

 

Total time for request: 3.99886918068 cURL ERROR -> 7: couldn't connect to host
pls help me

 

and some times its showing connect() timed out! ... not getting results pls reply soon

 

Is the remote server blocking the connection? E.g Firewall

 

thanks for ur reply........ we have already got through the firewall for our corresponding ip

/**

curl_close($ch);

/**

No, The problem still exists. Kindly give me a solution!!

 

pls can you explain how i will retrieve it from the target url ..

what site are you receiving information responses from? I know UPS has an XML barebones that can be interfaced with PHP in a few simple steps.
