Array sort keys numerically help
<pre><code>$test1[2] = "one";

$test2[1] = "two";
$test2[3] = "three";

$test = $test1 + $test2;

print_r($test);
</code></pre>

<p>I've used the array union operator but when i print the array it is in the wrong order.</p>

<pre><code>Array ( [2] =&gt; one [1] =&gt; two [3] =&gt; three ) 
</code></pre>

<p>How do i sort the keys numerically in the array?; so i get the below result.</p>

<pre><code>Array ( [1] =&gt; two [2] =&gt; one [3] =&gt; three ) 
</code></pre>
