Is exit needed after return inside a php function?
<pre><code>&lt;?php

function testEnd($x) {
    if ( ctype_digit($x) ) {
        if ( $x == 24 ) {
            return true;
            exit;
        } else {
            return false;
                 exit;
        }
    } else {
        echo 'If its not a digit, you\'ll see me.';
        return false;
        exit;
    }
}

$a = '2';

if ( testEnd($a) ) {
    echo 'This is a digit';
} else {
    echo 'No digit found';
}
?&gt;
</code></pre>

<p>Is exit needed along with return when using them inside a php function? In this case, if anything evaluated to false, i'd like to end there and exit.</p>
