Alternative usage of PHP return statement, alternative usage of phpreturn statement

Share another function of PHP return statement, a strange usage method seen in bbPress code.

I always thought that return can only appear in functions, until I looked at the bbPress code:

<?<span>php
</span><span>require_once</span>('./bb-load.php'<span>);

bb_repermalink(); </span><span>//</span><span> The magic happens here.</span>

<span>if</span> ( <span>$self</span><span> ) {
</span><span>if</span> ( <span>strpos</span>(<span>$self</span>, '.php') !== <span>false</span><span> ) {
</span><span>require</span>(<span>$self</span><span>);
} </span><span>else</span><span> {
</span><span>require</span>( BB_PATH . 'profile-base.php'<span> );
} // www.jbxue.com
</span><span>return</span><span>;
}</span>

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

Check the PHP manual: If you call the return statement in a function, it will immediately end the execution of this function and return its parameters as the value of the function. If called in the global scope, the current script file aborts running.
