Problem with simplexml functions
I've been using php for a little while and now want to start parsing xml documents with a view to storing user info etc. This is a newbie question, however I have searched the forum and still have the problem. When I attempt to execute a simplexml_load_file or simplexml_load_string function I get an error telling me I'm using an unknown function. I know that these functions work only with php5 and so have only two q's.
1. I'm sure that I have php5 installed as I installed it recently but how can I check?
2. I also know that I have to ensure that the simplexml extension in the php package is enabled. Could you tell me what file to look in what to set?
Thanks very much
