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 need to call the parent's constructor from ExtendedEmailer's constructor.

class ExtendedEmailer extends emailer
{
  function  __construct(){
    parent::__construct(null); 
  }

  // ...
}

otherwise $recipients is never initialized as an array.
