Another function of the PHPreturn statement, the return statement _ PHP Tutorial

Another function of the PHPreturn statement is the return statement. Another function of the PHPreturn statement is that the return statement always thinks that the return statement can only appear in the function until it reads the bbPress code: phprequire_once (. bb-load.php); bb_repermalink (); another function of PHP return statement, return statement

I always thought that return can only appear in the function until I read the bbPress code:

<?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' ); } return;}

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

Check the PHP Manual: if a return statement is called in a function, the execution of the function is immediately ended and its parameters are returned as the function value. If it is called globally, the current script file stops running.

Alas, the C language is too poisonous.

In PHP, how does return work?

Return is actually not difficult to use. it means return;

If return is executed, the content following the return statement will not be executed;
Return can be a function return value or a null value, depending on your usage, for example:

Function test ($ ){
If ($ a> 10 ){
Return "a> 10 ";
} Else {
Return "a <10 ";
}
$ B = 45;
$ C = $ B-$;
Echo $ c;
}

In this example, when you call this function and then give a number, it returns a string, and the code: $ B = 45;
$ C = $ B-$;
Echo $ c;
Will never be executed

Problems with using the return statement in PHP

Return is returned.
Echo is the output. You can also print
Return is not an output,
