数组中具有相同值的多个键

Question

Basically what I'm looking to do is have 2+ different keys pointing to the same value.

Something like:

"AP7898",
"AP7841"    => array('loadStatusLoad' => '.1.3.6.1.4.1.318.1.1.12.2.3.1.1.2',
                     'loadStatusStatus => '.1.3.6.1.4.1.318.1.1.12.2.3.1.1.3',                                      
               ),

both are ap7898 and ap7841 point to the values.

Answer 1

$val = 'hi';
$arr = array(
  'a1' => $val,
  'a2' => $val
);

or use references

$val = 'hi';
$arr = array(
  'a1' => &$val,
  'a2' => &$val
);


$val = 'bye'; // both are updated

Answer 2

Why not setup the parent array, setup the first key/value pair, and copy to the second?

$status = array( 'AP7898', 'AP7841' );

$status['AP7898'] = array('loadStatusLoad' => '.1.3.6.1.4.1.318.1.1.12.2.3.1.1.2',
                     'loadStatusStatus' => '.1.3.6.1.4.1.318.1.1.12.2.3.1.1.3');

$status['AP7841'] = $status['AP7898'];
