Answer 1

The basic task you can do with PHP is to define which XML file to transform with which XSLT script. Using this you can
a) pass parameters from PHP to XSLT and
b) use PHP functions in the XSLT script.
This example shows how - first PHP file:

registerPHPFunctions();
$proc->setParameter('', 'p', '123');
$proc->importStylesheet(DOMDocument::load("script.xsl"));
echo $proc->transformToXML(DOMDocument::load("data.xml"));
?>

second XSLT file:

The output should be 123456
EDITED: select="''" instead select=""
