PHP Return Statement Alternative usage

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

Always think that return can only appear in the function until the bbpress code is seen:

<?PHPrequire_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 ' );} Www.jbxue.comreturn;}

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

Check the PHP manual: If you call the return statement in a function, the execution of the function is terminated immediately and its arguments are returned as the value of the function. If called in the global scope, the current script file aborts the run.
