在PHP中将一些新数据添加到数组中

Question

I got an Array like this:

array('Testing'=>array(
'topic'=>$data['Testing']['topic'], 
'content'=>$data['Testing']'content'])
             ); 

Now I have got some new data to add into the Array shown aboved,
how can I do it so that the new Array will look like this:

array('Testing'=>array(
'topic'=>$data['Testing']['topic'], 
'content'=>$data['Testing']['content']),
'new'=>$data['Testing']['new'])
                 ); 

Could you help me please?

In the same way that you can access arrays values by key, you can set by key, as well.

<?php
$array = array('foo' => array('bar' => 'baz'));
$array['foo']['spam'] = 'eggs';
var_export($array);

Output:

array (
  'foo' => 
  array (
    'bar' => 'baz',
    'spam' => 'eggs',
  ),
)
