Php Curl With Xml Not Working

Solution 1:

You should be using rawurlencode instead of htmlentities, and only on the XML part of the 'payload'. Also, you're defining your constant to the literal text "$xml" by using single quotes around your variable. So replacing those two lines with these should do:

$xml = 'xml_text='.rawurlencode('<?xml … </idibu>'); # <-- insert entire XML there

define('XML_PAYLOAD', $xml);
