Sending and Recieving XML via cURL

Discussion in 'PHP' started by cesarcesar, Aug 4, 2007.

    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.
    SEMrush
    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):

    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.

    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.

    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.
