In Yii2 how to use array index as $key when using ArrayHelper::map() method?
<pre><code>$lang = [
   'en' =&gt; ['id'=&gt;'1', 'name' =&gt; 'English', 'short' =&gt; '1', 'active' =&gt; '1',],
   'tn' =&gt; ['id'=&gt;'2', 'name' =&gt; 'Tamil', 'short' =&gt; '2', 'active' =&gt;'1',],
]; // sample array`    
</code></pre>

<p>In yii2 i can use the array map method as follow.
<code>
ArrayHelper::map($lang,'id','name');</code></p>

<p>But how to put the array index ('en' and 'tn') in the place 'id' 
<code>
ex:ArrayHelper::map($lang, array_index,'name');</code></p>

<p>thanks</p>
