First of all, I have tried researching with Google to no success. I have a web service that is returning XML, but I can not find a way to parse it that works. I have tried simplexml in many different ways and it's just not working. I am unexperienced with PHP and could use some help. I am creating an website that uses this web service or one just like it to get its information. I need to be able to pick out certain data from the XML and use it in my code.

 <?php

$url = "https://my-test.illinoisstate.edu/service/it363/directory";
$params = array(
	"uid" => "833330103"
);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_POST, count($params));
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));

$result = curl_exec($ch);
curl_close($ch);

header("content-type: text/xml");
echo $result;

$xml = simplexml_load_string($result);

echo $xml['uid'];

I would expect line #24 not to work. afaik, SimpleXMLElement does not implement the ArrayAccess interface. so I’d go for $xml->uid.

Thanks, but I have tried and that doesn't show anything either.

then your only choice is to make a dump: var_dump($xml);

If in doubt, always var_dump() variable to see what's actually inside. Guessing is no good, really.
