<p>I guess the main question is what is the difference between the 3 exactly?</p>

<p>What is the correct semantic usage for each one of these?</p>

<p>From what I see <code>return false;</code> can discontinue a function whereas <code>die();</code> and <code>exit();</code> will prevent any further code running <em>at all</em>.</p>

<p>Is this correct?</p>
