1. How are session variables accessed?

A. Through $_GET

B. Through $_POST

C. Through $_REQUEST

D. Through global variables

E. None of the above

Answer:

    Although session data can be accessed using the global variables if the register_globals INI setting is turned on, the exam uses a version of PHP configured using the default php.ini file found in the official PHP distribution. In recent versions of PHP, the register_globals setting is turned off by default because of its serious security implications. As a result, Answer E is correct.

Your Answer: ____________________________
