[foaf-protocols] FOAF+SSL: Inserting a Public Key into a Remote Profile Using SPARUL

[Melvin Carvalho]

Short PHP script to insert a FOAF+SSL public key remotely using SPARUL
and HTTP POST.

I've removed all bnodes in this, and have hardcoded four anchors,
which might not be the best style, but it works.

#cert
#modulus
#public_exponent
#me

Hope this is useful, let me know if you think of any way of improving this.

<?php

function postSparul($uri, $sparul)
{
	$c = curl_init();
	curl_setopt($c, CURLOPT_URL, $uri);
	curl_setopt($c, CURLOPT_POST, true);
	curl_setopt($c, CURLOPT_POSTFIELDS, $sparul);
	curl_exec ($c);
	curl_close ($c);
}

$webid = 'http://foaf.me/test';
$public_exponent = 65537;
$modulus = 'B5EBEFF72746A12FB96BE4FF73959C5163D342BF21A1046DBD3EE181FC6654D29903AE97764D8E8CBAF4B830A79073BECD0AAAD5FC9C9847551A9CEF548AE2CDFD4F0B6578CD31CEB711EEFF0CB7F9F922FA107CCDCE4832CCB51D7C319069168DEE3801F5490F6D21BD8211918F40749A99A4ECDF872AA59CA861AC36D010B1';
