If you like to read the XML from HTTP whit a POST request, you can use libxml_set_streams_context.
Example:
<?php
$param = array('http' => array(
'method' => 'POST',
'header' => "Content-type: application/x-www-form-urlencoded\r\n",
'content' => http_build_query(array(
'post_param1' => 'value1',
'post_param2' => 'value2',
)),
));
libxml_set_streams_context(stream_context_create($param));
$reader = XMLReader::open('https://example.com/get.php?get_param=value3');
?>When using the XmlReader to read local XML files, remember it the open function requests a URI. Add 'file://' to the front of the FULL path to the XML. Otherwise you may get:
PHP Warning: XMLReader::open(): Unable to open source data in ...XML can optionally declare its own encoding:
<?xml version="1.0" encoding="UTF-8"?>
You can use the $encoding parameter to provide this information (if missing) or override it (if wrong).
Output is always UTF-8 (that's how libxml works).Windows users remember to enable php_openssl.dll in your php.ini if you want to be able to use this function (and others) with a HTTPS URL.For some reasons, the open() method keep throwing me this error :
PHP Warning: XMLReader::open(): Unable to open source data in /var/www/nota/ethamap/fat_xml.php
It doesn't make sense as the xml file target hosted on my server is perfectly reachable. Adding this line before invoking open() fixed it :
libxml_disable_entity_loader(false);

It is somehow related.
