Sorry the question was answered:<br><pre><code class="code-1 nolinks" id="code-20-43047651-1">$result = array_map(function($el) {    return $el['order_id'];
}, $arr);</code></pre>
</div>


Sorry the question was answered:


$result = array_map(function($el) {    return $el['order_id'];
}, $arr);

<div>
Although answered, is it possible to do the same but referencing by column number instead of the name 'order_id' ?

The following is simpler, but only seems to work naming the column:<br><br><pre><code class="code-1 nolinks" id="code-20-43047667-1">$arr_order_id = array_column($rows, 'order_id');</code></pre>
</div>

$arr_order_id = array_column($rows, 'order_id');

I want to extract a column from a nested array, example:<br />
<br />
Array<br />
&nbsp; &nbsp; (<br />
&nbsp; &nbsp; &nbsp; &nbsp; [0] =&gt; Array<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; (<br />

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; [order_id] =&gt; 6127<br />
&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; )<br />

&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; )<br />
<br />
&nbsp; &nbsp; )<br />
<br />
This is what I need:<br />
<br />
$results = array()<br />
$results(6127, 6123)<br />
<br />
I'd like to do this concisely eg with an array_map or similar<br />
