Making a REST API request in PHP - php

Question

Apologies for newbishness of this question. I'm looking into integrating one website's API into my own website. Here's some quotes from their documentation:
At the moment we only support XML,
when calling our API the HTTP Accept
header content type must be set to
“application/xml”.
The API uses the PUT request method.
I have the XML I want to send, and I have the URL I want to send it to, but how do I go about constructing a suitable HTTP Request in PHP that will also grab the XML that's returned?
Thanks in advance.

You can use file_get_contents and stream_context_create to create a request and read the response. Something like this will do it:
$opts = array(
"http" => array(
"method" => "PUT",
"header" => "Accept: application/xml\r\n",
"content" => $xml
)
);
$context = stream_context_create($opts);
$response = file_get_contents($url, false, $context);

This is actually what worked for me:
$fp = fsockopen("ssl://api.staging.example.com", 443, $errno, $errstr, 30);
if (!$fp)
{
echo "<p>ERROR: $errstr ($errno)</p>";
return false;
}
else
{
$out = "PUT /path/account/ HTTP/1.1\r\n";
$out .= "Host: api.staging.example.com\r\n";
$out .= "Content-type: text/xml\r\n";
$out .= "Accept: application/xml\r\n";
$out .= "Content-length: ".strlen($xml)."\r\n";
$out .= "Connection: Close\r\n\r\n";
$out .= $xml;
fwrite($fp, $out);
while (!feof($fp))
{
echo fgets($fp, 125);
}
fclose($fp);
}
