<?php

// Here's some data
$fields=array( "Height" => "5",
	"Cabinet" => "76",
	"Label" => "Test_Api",
	"DeviceType" => "Chassis",
	"Owner" => "23",
	"Position" => "5"
);

//url-ify the data for the POST
function stringify($fields){
	$fields_string="";
	// Sanitize your data here
	foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
	rtrim($fields_string, '&');

	return $fields_string;
}

// create curl resource
$ch = curl_init();

// set url
curl_setopt($ch, CURLOPT_URL, "http://dev.opendcim.org/api/v1/device/${fields['Label']}");

curl_setopt($ch, CURLOPT_USERPWD, "dcim:dcim");
curl_setopt($ch, CURLOPT_POST, count($fields));
curl_setopt($ch, CURLOPT_POSTFIELDS, stringify($fields));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "PUT");

// $output contains the output string
$output = curl_exec($ch);

print_r($output);

// close curl resource to free up system resources
curl_close($ch);      

This here should really have some url encoding applied but this was a simple example and I couldn't be bothered.
