PHP Return statement alternative usage is not only in the function

Share another function of the PHP return statement, a wonderful way to see it in the Bbpress code.

Always assume that return can only appear in the function until you see the bbpress code:


Require_once ('./bb-load.php ');

Bb_repermalink (); The magic happens here.

if ($self) {

if (Strpos ($self, '. php ')!== false) {

Require ($self);

} else {

Require (Bb_path. ' profile-base.php ');




Does return still appear outside the function? This is unthinkable in C language.

Checked the PHP manual: If you call the return statement in a function, it ends the execution of the function immediately and returns its arguments as the value of the function. If invoked in the global scope, the current script file aborts.
