break; statement in PHP function
<p>I'm reading through code I've just been assigned, and amid many <code>case</code> statements is a single, lone <code>break;</code>.  It's not wrapped in any <code>switch</code> statements.  It's just there, and doesn't seem to have any purpose.  I'm new to PHP, is this some advanced code use, or just leftover code?</p>

<p>Here's the code:</p>

<pre><code>function foo() {
...many for/switch statements (all with closing brackets)...
    break;
...other code....
}
</code></pre>
