Using array_push in method in php

Question

The addRecipients use push_array but it does not work. What am I doing wrong here??

In class.emailer.php

class Emailer
{
public $sender;
public $recipien         


        

Answer 1

You are probably not initiating $recipients when you rewrote the constructor.

class Emailer {
    public $recipients = array();

    function __construct($sender)
    {
        $this->sender = $sender;
    }

Should do it. Check your warnings for
