PHP check if arrays are identical?
<p>I'm looking for a way to check if two arrays are identical, for example</p>

<pre><code>  $a = array(
    '1' =&gt; 12,
    '3' =&gt; 14,
    '6' =&gt; 11
);
$b = array(
    '1' =&gt; 12,
    '3' =&gt; 14,
    '6' =&gt; 11
);
</code></pre>

<p>These two would be identical, but if a single value was changed, it would return false, I know I could write a function, but is there one already built? </p>
