PHP XML HTTP Post

[5speed]

Hello,
I am having troubles sending xml through an http post with php. Does anyone know of a good site that has examples on doing this?
Thanks in advanced.

what do you want to do?
Do you want to call a URL and POST a xml file?

Read the user notes at: http://www.php.net/manual/en/ref.http.php or let me know what you need specifically.
