Receive the posted XML data
In order to test the posted data, we can create a file creation steps to ensure that we receive the posted data via the $_POST array
<?php
/*
File name: postdata2.php
*/
$xmlFile = "xmlFile.txt";
$fh = fopen($xmlFile, 'w') or die("Cannot open file");
fwrite($fh, $_POST["xmldata"]);
fclose($fh);
?>
During integration projects or during such similar situations you may have across a necessity to transfer XML data or plain text file across server locations.
Curl comes in handy during such scenarios. Following program is used to post XML data using Curl. In order for Curl to function, ensure that PHP settings has the curl module installed and that the libraries/dll libeay32, ssleay32 is installed in your server.
<?php
/*
File name: postdata.php
*/
$post_url = "http://localhost/demo/postdata2.php";
$xml_string = '<?xml version="1.0" encoding="UTF-8"?>
