Why we use return in the end of function while not returning any value
<p>I am confused about return statement , why we need to use return in end of function , for example</p>

<pre><code> function test($a){blah;
                   blahh ;
                   blahhh;
                  blahhhhh;
                    return;}
</code></pre>

<p>What the use of return here? Function automatically terminates when all the statements executed , I think there is no use of return here , but this picture from <a href="http://www.w3resource.com/php/statement/return.php" rel="nofollow noreferrer">http://www.w3resource.com/php/statement/return.php</a> make me confused<a href="https://i.stack.imgur.com/eKInj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/eKInj.png" alt="enter image description here"></a></p>

<p>So
Can someone please explain the  use of return (when we not returning any value).</p>
