Is function always return a value?
no, every function can not return a value. for example void name() { cout<<"Hello world"; } this function does not return any value due to the key word void that tells the compiler that the function does not returns a value.
What part of a function definition specifies the data type of the value that the function returns?
The function header. The return value is written before the name of the function. This return type must match the type of the value returned in a return statement.

What is a return statement used for?
It means end the function. Functions automatically end when execution reaches the end of the function, but you can return from a function at any point within the function with a return statement.

Can you call a function inside an echo statement in PHP?
Of course it is possible to call a PHP-function inside an echo statement. The function will be executed and returns a value. This value then is used in the echo statement. For example: echo "Ferengi-Rule #1: ", ferengi_rule(1), "\n"; echo "Random: ", ferengi_rule(0), "\n"; function ferengi_rule($number) { $rules = array( 1 => "Once you have their money, never give it back.", 2 => "You can't cheat an honest customer, but it never hurts to try.", 3 => "Never buy anything for more than is absolutely necessary.", 4 => "Sex and profit are the two things that never last long enough." // ... ); if( isset($rules[$number]) ) { return $rules[$number]; } else { return array_rand($rules); } }
What is the difference between echo and print and printf in PHP?
The print function is slightly more dynamic than the echo function by returning a value, and the echo function is slightly (very slightly) faster. The printf function inserts dynamic variables/whatever into wherever you want with special delimiters, such as %s, or %d. For example, printf('There is a difference between %s and %s', 'good', 'evil') would return 'There is a difference between good and evil'.

When a function does not return a value what kind of function is it called?
In most computer languages, a procedure that returns a value is called a function and a procedure that does not return a value is called a subroutine or subprogram. Usually the languages treat the passing of arguments/parameters differently between functions and subroutines. The C language does not distinguish between them. A subroutine that does not return a value is define as a "void" function indicating that no return value is used or available.
