I have a hash of arrays. Each site in this case has a minimum amount of items and a list of items. If a site dosen't have enough items I want to move those items to a different site.
I have solved the issues of deciding when and which site and I can already use shift to move each item one at a time.

However, the number of items could be large and I'm looking for a quicker way.
I want to know if I can somehow append the reference to the array to the end of another array and then de-reference the original 'pointer'. This should in theory be very quick. 
$VAR1 = 'insert';
$VAR2 = [
          {
            'weight' => '',
            'barcode' => '',
            'flag' => ''
          }
        ];
$VAR3 = 'stream';
$VAR4 = [
          {
            'site' => [
                        {
                          'tosite' => '',
                          'runamt' => '',
                          'comboid' => '',
                          'minamt' => '',
                          'items' => [],
                          'tostream' => ''
                        }
                      ],
            'maxsheet' => '',
            'minsheet' => '',
            'colour' => '',
            'maxweight' => '',
            'state' => {},
            'duplex' => ''
          }
        ];
$VAR5 = 'paper';
$VAR6 = '';
