Hi !
I am the beginner of PHP4, here is my questions:

1) What is the different between $var and $$var ?? What is it's function ?? How to use it ?

2) How to use WDDX ?? What should I need ?
3) Just PHP4 "communicate" with microsoft Access (ODBC), just like ASP ?? What should I do ?

1)

$$var is a variable variable (no typo)
it means you can make a new variable that will have the name of the content of the old variable:

$old_var="new_var";
$$old_var="hello";
echo $new_var;

will print "hello"

2) read php the manual and do a search on the internet
3) Check out the columns section on this site for more info.
