[RESOLVED] Need help send Request to webservice and get XML responce

oceangirl

Hello!
I am new to php. And I am in a BIG trouble now. 🙁
Can someone help me, please?!

I am creating my own client, who will send Request to webservice,
for example with URL
$url = "http://api.bart.gov/api/route.aspx?cmd=routes&key=XXXX";
and will receive XML responce.

How can I implement that?

Thank you very much!

You could use the [man]cURL[/man] functions to execute the HTTP request, then parse the response. If it is a SOAP or XML-RPC service, you could use the PHP [man]SOAP[/man] or [man]XML-RPC[/man] extensions. If it is RESTful, I'm not aware of any built-in extensions, but there are more than likely any number of 3rd party packages you could use.

I tried curl, but something wrong! 🙁
This is a REST architecture.

This is my code:

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://api.bart.gov/api/route.aspx?cmd=routes&key=RASV-P9D8-TU75-6MX2');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$contents = curl_exec ($ch);
echo $contents;

echo "<p>new line xml = new SimpleXMLElement(contents); xml->root->routes->route->name<p>";

$xml = new SimpleXMLElement($contents);
echo $xml->route[0]->name;
// nothins is printed

Why the last

echo $xml->route[0]->name;

do not print nothing to me???
I think nothing is printed because my response is a string. How can I get XML response?
Or how I can create XML from my string?

Actually the correct XML should be like this:

XML Results

Sample

<?xml version="1.0" encoding="utf-8" ?>
<root>
<uri><![CDATA[ http://api.bart.gov/api/route.aspx?cmd=routes ]]></uri>
<sched_num>26</sched_num>
<routes>
<route>
<name>Pittsburg/Bay Point - SFIA/Millbrae</name>
<abbr>PITT-SFIA</abbr>
<routeID>ROUTE 1</routeID>
<number>1</number>
<color>#ffff33</color>
</route>
...
</routes>
<message />
</root>

thank you very much.

Looks like you missed the <routes> (plural) element. also, route[0] will be an object, so you might need to access each of its children separately:

echo $xml->routes->route[0]->name; // Pittsburg/Bay Point - SFIA/Millbrae
