Integrating PHP Curl - php

Question

I have the code below which calls up an MySQLi and presents it in XML form in my browser.
The next stage is that instead of presenting it in my browser I want to send it to another IP address using PHP Curl. Please can someone help me with the extra code needed to do that.
<?php
$mysqli_connection = new MySQLi('localhost', 'root', 'secret', 'edgeserver');
if ($mysqli_connection->connect_error) {
echo "Not connected, error: " . $mysqli_connection->connect_error;
}
$sql = "SELECT SessionLogs.sessionid, SessionLogs.eventid, BetStatus.BetStatus, EventStatus.EventStatus, SessionLogs.activestatusid
FROM SessionLogs INNER JOIN
EventStatus ON SessionLogs.eventstatusid = EventStatus.EventStatusID INNER JOIN
BetStatus ON SessionLogs.betstatusid = BetStatus.BetStatusID
where ActiveStatusID = 1
";
$res = $mysqli_connection->query($sql);
$xml = new XMLWriter();
$xml->openURI("php://output");
$xml->startDocument();
$xml->setIndent(true);
$xml->startElement('Alive');
$xml->writeAttribute('timestamp', date('c'));
if($res === FALSE) {
die(mysqli_error()); // TODO: better error handling
}
while ($row = mysqli_fetch_assoc($res)) {
$xml->startElement("Event");
$xml->writeAttribute('sessionid', $row['sessionid']);
$xml->writeAttribute('eventid', $row['eventid']);
$xml->writeAttribute('BetStatus', $row['BetStatus']);
$xml->writeAttribute('EventStatus', $row['EventStatus']);
$xml->writeAttribute('activestatusid', $row['activestatusid']);
$xml->endElement();
}
$xml->endElement();
$xml->endElement();
header('Content-type: text/xml');
$xml->flush();
?>
Please help. Thanks.

Answer 1

You can send xml data using curl with following code
$input_xml = ''; //XML Data
$url=''; // URL
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POSTFIELDS,
"xmlRequest=" . $input_xml);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 300);
$data = curl_exec($ch);
curl_close($ch);

Use $xml->openMemory(); and $xmlString = $xml->outputMemory() to catch the cache of your XMLWriter-Object (Documentation).
