PHP return Statement

Description

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.

Syntax

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