Trying to grab xml data through a url

[andy1212]

Hey, I'd like to grab xml data by passing get variables through an https ssl secured url and then parse it. What would be the best way to go about doing that and is there a solid tutorial with step by step on how to do that? Thanks for your time!

$url = "http://www.example.com/path/to/page?"; // with the question mark

$get = array("key 1" => "value 1", "key 2" => "value 2", "key 3" => "value 3" /* ... */);

$xml = new SimpleXMLElement($url . http_build_query($get), 0, true);

From there you have a SimpleXMLElement that you can do pretty much anything you want with. What do you want to do? What kind of XML are you getting back?

its not http:// its https:// and ssl secured so I need to handshake or authenticate with the page before grabbing the xml data and bringing it back to me webpage. The url looks like this,

 

I have the url setup like this,

$xml = '
weight_system="IMPERIAL" shipper_number="000222000" destination_postal_code="'.$data5['zip'].'" service_type="1"
';


$xml2 = '
total_pieces="'.$value.'" total_weight="'.$weight.'"
'; 


$token = 'token'; 
$base_url = 'https://www.shippingco.com/XML/RatingXML.jsp'; 


$request_url = $base_url . '?' . http_build_query(array(
     'shipment' => '<shipment ' . $xml . '><total ' . $xml2 . '/></shipment>',
       'token' => $token
));

I have an RSA key, SSL cert, CA bundle and password and need to use that information to authenticate with the url to grab the xml data. and xml example

 

 

<rating xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.shippingco.com/XML/rating.xsd">
<rate weight="5.0" weight_unit="lb" zone="3" transit_time="1" transit_time_guaranteed="false" estimated_delivery_date="2013-07-26" base_charge="11.05" freight_charge="11.05"residential_address_charge="2.75" net_charge="13.80" fuel_surcharge_rate="15.8" fuel_surcharge="1.75" subtotal_charge="15.55" on_hst_charge="2.02" total_charge="17.57"/>
</rating>

So how would I go about doing that?

Nope. What have you discovered in the last 24 hours?

If you want to actually built the TCP/IP packets yourself then sure, go ahead and climb that mountain. But the rest of us don't mind letting PHP and our operating system do that work for us.

 

Or to be more blunt, are you saying

file_get_contents($request_url)

does not work?

[andy1212]

I tried file_get_contents($request_url) and I don't know if it works or not because when I try echoing out $result, nothing is echoed. When I try var_dump($result) I get bool(false) so how do I know it's working... Shouldn't xml data be echoed?

Nvm you were right, simplexml_load_file($request_url); worked! When echoing out it echoed out the xml!!! Finally I can move on to figure out how to parse it lol thanks so much!
