Which of the following that can be use to access session variables in PHP?
Neko [114]

Answer:

a. $_SESSION

Explanation:

A session variable in PHP can be accessed using the global variable $_SESSION.

This can be used for both setting and retrieving session values as described subsequently.

$_SESSION["var1"] = "value1";

This set a session variable called 'var1' to a value 'value1'. Later if we want to retrieve this value we can do it as follows:

echo "Value of session variable 'var1' is " . $_SESSION["var1"] ;

This will print the result: Value of session variable 'var1' is value1

Look at the following function prototype. double mynewFunction(int); What is the data type of the function’s return variable?
nadezda [96]
The answer is A) Double.

The return type is specified before the method's signature, and the signature is composed of the the method's name and parameters.

In this case, the method is named mynewFunction, takes in an integer as a parameter, and returns a double.

Also, fun fact which is kind of unrelated: if two or more methods have the same name, they can have different functionality as long as their signature is different (different parameter types).
