A variable is a reference to a single object (often a number, character, or string of characters).
An array is a reference to a contiguous block of memory in which zero or more individual objects.
Elements of the array.
congugative memory allocation ,is use to array
There are no relations between different variables. If you want to enable a relationship between variables, you must write the code to implement that relationship. Encapsulating the variables within a class is the most obvious way of defining a relationship between variables.
Simple non-array variables are usually passed to methods by value.
Object array is called universal array because it can store multiple variables of the same type
Full representation of an array begins from the index 0 and ends at n-1 where n is the number of variables of the array.

The extent of changes between the variables throughout different conditions or circumstances.
The $_POST array contains only variables supplied by a form that used the POST method, while the $_REQUEST array combines the $_POST, $_GET and $COOKIE arrays.
They will have different variables, in different configurations.
For global/static variables: yes.For auto variables: no.
There is no such thing as "the usual sampling distribution". Different distributions of the original random variables will give different distributions for the difference between their means.There is no such thing as "the usual sampling distribution".
