Subject: XSL Extension
From: irchtml@php.net (Kenneth Schwartz)

I'm documenting the new XSL extension and needed a little clarification
on the two XSL functions in the PHP namespace [function() and
functionString()].  In what case would either of these XSL functions be
called?  As I understand it php:function() only allows string parameters
to the handling PHP function whereas php:functionString() allows passing
element values to the function.

Examples:
<xsl:value-of select="php:function('date', 'r')"/>
Outputs the RFC formatted date (current date/time)

<xsl:value-of select="php:functionString('date', 'r', date)"/>
Outputs the RFC formatted date of the <date> element as the unix
timestamp

I just wanted to be sure of what I've gathered from testing and the
source that the usage of both functions is correct.  Any other
information would be appreciated.

Thanks,

Kenneth
