PHP return Statement


PHP return statement immediately terminates the execution of a function when it is called from within that function.

This function is also used to terminate the execution of an eval() function or script file.

If this function is called from a global scope, the function stops the execution of the current script. If the current script file was included using include() or required(), then control goes back to the calling file.


return expression 

Where expression is any valid expression. Note that, since the return is not a function but a language construct, using parenthesis is not required.

PHP: Tips of the Day

PHP: PHP Constants Containing Arrays?

NOTE: while this is the accepted answer, it's worth noting that in PHP 5.6+ you can have const arrays

You can also serialize your array and then put it into the constant:

# define constant, serialize array
define ("FRUITS", serialize (array ("apple", "cherry", "banana")));

# use it
$my_fruits = unserialize (FRUITS);
