Collections provide a method <code>map</code> which allows you to iterate your collection and add/modify fields.

<pre><code>function modify_net_commision($var) {
 return YOUR_LOGIC_HERE;
}

$collection = [
 [ "userId" =&gt; 1, "name" =&gt; "Sim Aufderhar", "net_commission" =&gt; null ],
 [ "userId" =&gt; 2, "name" =&gt; "Carolyn Lang III", "net_commission" =&gt; null ],
];

$external_var = 'I will be used on modify_net_commision function';

$new_collection = collect($collection)-&gt;map(function ($arr) use ($external_var) {
 $arr['net_commission'] = modify_net_commision($external_var);
 return $arr;
})
</code></pre>

If you want to remove some fields from your collection, use <code>reject</code> method.

My collection:

<pre><code> ($usersWithCommission) Illuminate\Support\Collection {#2625
 #items: array:2 [
 0 =&gt; array:3 [
 "userId" =&gt; 1
 "name" =&gt; "Sim Aufderhar"
 "net_commission" =&gt; null
 ]
 1 =&gt; array:3 [
 "userId" =&gt; 2
 "name" =&gt; "Carolyn Lang III"
 "net_commission" =&gt; null
 ]
 ]
}
</code></pre>

I would like modify the net_commission property, but I can not:

<pre><code>foreach ($soldProperties as $property) {
 if (!$property-&gt;buyer_user_id &amp;&amp; !$property-&gt;seller_transferring_user_id) {
 $usersWithCommission-&gt;where('userId', $property-&gt;user_id)-&gt;first()['net_commission'] += $property-&gt;net_commission_of_sold;
 }
 }
</code></pre>

How I can?
