phpinfo problem

Just one problem.  The traditional "Hello World," program that my book 
starts off with includes a PHP function called, phpinfo()--prefaced by a 
print command.  It's supposed to print out a rather large amount of 
information in the form of a table.

Have you ever head of this function?  It won't work for me.  It just prints 
a ton of code, instead of printing the table.  Is there a good place where I 
can get an entire list of all PHP functions?  Or doesn't that exsist?

Hello:

	Have you activated the display_errors directive in your php.ini,which is in
your Windows Folder ?

	The Php manual contains a function reference.
