Question

I would like to echo the results of this array in a readable format “[id], [reason], how can I do that?

$s1 = "SELECT DISTINCT `id`, `reason` FROM wlp_$this->client.lu_unallocation_reasons";
        $m1 = $this->conn1->_execute($s1);
        while ($r1 = $this->conn1->_nextRow($m1)) {
            $reasons[] = array('id' => $r1['id'], 'reason' => $r1['reason']);
        }

What you need is a foreach loop.

foreach($reasons as $reason){
   echo "ID: ".$reason['id']."<br>";
   echo "Reason: ".$reason['reason']."<br>";
}
