Sorting multi-dimensional array based on value of specific key in array
<p>I have an array which is something like this:</p>

<pre><code>    $array[] = array(
        "name" =&gt; "sample",
        "image" =&gt; "sample.jpg",
        "header" =&gt; "sampleDelights",
        "intro_copy" =&gt; ""
    );
    $array[] = array(
        "name" =&gt; "lwmag",
        "image" =&gt; "lwmag.jpg",
        "header" =&gt; "LW Mag",
        "intro_copy" =&gt; ""
    );
</code></pre>

<p>I want to sort this array based on the alphabetical order from the key "header" with PHP. I have tried usort and searched for built in functions but cannot find one (or looking past it). Is this possible with a single php function?</p>
