Utterly lost the plot with arrays

[Charisma Bypass]

$this->domestic_types = array(
             '01' => 'Priority (by 10:30AM, later for rural)',
             '03' => '2 Day Air',
             '05' => 'Standard Overnight (by 3PM, later for rural)',
             '06' => 'First Overnight',
             '20' => 'Express Saver (3 Day)',
             '90' => 'Home Delivery',
             '92' => 'Ground Service'
      );

Instead of that, I want to do this:

$this->domestic_types = array();

and then add the others into it, one by one.

Should be easy, but cannot see the woods for the trees

Thanks in Advance.

Ug.  Please can I go to bed.

 $result = array();
           
 $result['01'] = 'Priority (by 10:30AM, later for rural)';
 $result['03'] = '2 Day Air';
 $result['05'] = 'Standard Overnight (by 3PM, later for rural)';
 $result['06'] = 'First Overnight';
 $result['20'] = 'Express Saver (3 Day)';
 $result['90'] = 'Home Delivery';
 $result['92'] = 'Ground Service';

 $this->domestic_types = $result;
