PHP - Reference to Array - how to?

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 ?

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

When you write $variable = array[key][key]... you are passing value of the array to the variable. If you want to change value of array itself you need to do it like this:

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

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

print_r($myArray);

I know that i can do it this way - but in my problem i have to solve it is not possible to call the array like this and i have to create a reference to change it.
