PHP - 对数组的引用 - 如何？

Question

I want to do something like this:

$myArray = array(
'1' => array('2' => array('3' => 'Test'))
);

$changeIt = $myArray['1']['2']['3'];
$changeIt = 'Changed Test';

// $myArray['1']['2']['3'] is now "Changed Test"

Are there ways to do this ?

Answer 1

You can do like this:

$myArray = array(
'1' => array('2' => array('3' => 'Test'))
);

$myArray['1']['2']['3'] = &$changeIt;//reference
$changeIt = 'Changed Test'; 
echo  $myArray['1']['2']['3']; //Changed Test

$changeIt = 'Another test';
echo $myArray['1']['2']['3']; //Another test
