How would I pass a variable from flash to php?
I've been in many tutorials in the net but I cannot understand much of the tutorials...
I only saw same method like using URLRequest & URLLoader with the location of the php files then the variables in the php which connects to the database is accessible.
All are accessing the php not passing flash variables to the php file like in the above code.
All help is greatly appreciated.

Answer 1

that's really poor as2 coding so it will translate to really poor as3 coding.
but, to answer your question, you assign a data property to your urlrequest to convey data from flash to php.  the data property will be a urlvariables instance and you assign variables/values to your urlvariables instance:
var urlVar:URLVariables=new URLVariables();
urlVar.eid=whatevervalue;
urlVar.rdoc=whatever;
urlVar.str=whateverelse;
yourURLRequest.data=urlVar;
