Took me a while to get a working example.  Here it is:
<?php
# enable warnings
ini_set( 'track_errors', 1);
ini_set('error_reporting', E_ALL | E_STRICT);
# this is a sample relaxNG definition
$rng = <<<EOT
<?xml version="1.0" encoding="UTF-8"?>
<grammar ns="" xmlns="http://relaxng.org/ns/structure/1.0"
 datatypeLibrary="http://www.w3.org/2001/XMLSchema-datatypes">
 <start>
   <element name="apple">
     <element name="pear">
       <data type="NCName"/>
     </element>
   </element>
 </start>
</grammar>
EOT;
# well formed xml, but invalid per schema
# too many pears
$bad_xml =<<<EOT
<?xml version="1.0"?>
<apple>
 <pear>Pear</pear>
 <pear>Pear</pear>
</apple>
EOT;
# well formed xml and valid per schema
$good_xml =<<<EOT
<?xml version="1.0"?>
<apple>
 <pear>Pear</pear>
</apple>
EOT;
# this function does the work, it tests the relaxNG in the string $rng
# against the xml in string $xml
Function relaxNG ( $xml, $rng ) {
       $dom_xml = new DomDocument;
       $dom_xml->loadXML($xml);
                       
       if ( $dom_xml->relaxNGValidateSource ( $rng ) ) {
               echo "Good\n";
       } else {
               echo $php_errormsg . "\n";
       }
}      
# test the good xml, will echo:
#    Good
relaxNG ($good_xml, $rng);
                       
# test the bad xml, will echo:
#    Did not expect element pear there
relaxNG ($bad_xml, $rng);
?>
results:
Good
Did not expect element pear there
