How do PHP compare arrays
<p>Considering two PHP arrays with a single element:</p>

<pre><code>$left = array(
  230985 =&gt; "/A/B/C/D"
);
</code></pre>

<p>and </p>

<pre><code>$right = array(
  223372 =&gt; "/A/B/C"
);
</code></pre>

<p>On this statement:</p>

<pre><code>if($left &lt;= $right)
</code></pre>

<p>How do PHP will compare these arrays to determine an order between them?</p>

<p>Comparing two strings will use an alphabetical order, but what's the behavior for arrays?</p>
