<?php

$array = [['Example' => 'Value']];

function hello(&$array) {
    foreach ($array as &$member) {
        $member['Test'] = true;
    }
}

var_dump($array);

Consider the above. Why is it that ‘Test’ => true is not added to the array member [‘Example’ => ‘Value’]?

I’ve passed references down the line, so $member should be a name referring to the content [‘Example’ => ‘Value’]. I’ve even removed the & from &$member, and it is still not working. What am I misunderstanding about PHP references here?
