web apps using php to generate xml

[petermichaux]

Hi,

I'm interested in building database web applications. A perfect example
of what I want to do would be an e-commerce website with php, xml, xsl,
css, pear db and mysql. I understand the basics of the technology parts
seperately but I would like to read about integrating them and managing
the files (directory structure). Any books or sites that cover this
integration or parts of it?

Thank you,
Peter

good ideas here too. thanks.]
