Question

I want to send a put request to an API which wants the details of the request as XML

Apparently I need to send the xml as a file when using PUT with PHP.

How can I do this?

Here is what I’m trying:

$HttpSocket = new HttpSocket();
$result = $HttpSocket->put($put, $fh);

where $put is the url and $fh is a file i have made on the fly like this

$xmlObject = Xml::fromArray($xmlArray);
$xmlString = $xmlObject->asXML();

$fh = fopen('php://memory', 'rw');  
fwrite($fh, $xmlString);  
rewind($fh);

I ended up doing this just using php rather than the php helpers

# write data into a temporary file
$putData = "<subscription><productPath>$new_product_path</productPath></subscription>";
$putDataFile = tmpfile();
fwrite($putDataFile, "<subscription><productPath>$new_product_path</productPath></subscription>");
fseek($putDataFile, 0);

# initialize PUT call
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://api.example.com");
curl_setopt($ch, CURLOPT_PUT, true);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); 
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPHEADER, array("Content-Type: application/xml"));
curl_setopt($ch, CURLOPT_INFILE, $putDataFile);
curl_setopt($ch, CURLOPT_INFILESIZE, strlen($putData));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

# executes PUT call and clean up
$result = curl_exec($ch);
$info = curl_getinfo($ch);
fclose($putDataFile);
curl_close($ch);

I’d have preferred using the Cake classes for neatness, but this works with the api i was using.
