PHP Multidimensional Array Access

问题

Say I have a multidimensional array in PHP such as:

this_array= array(
    string_name=>'string', 
    string_array=>array(
        'string_key'=>'string_val'
    )
)

How am I to access string_array's key-val pairs? Is it just:

this_array['string_array']['string_key'] 

Or is it something different?

回答1:

Code should look something like this, if you were intending on using strings as your keys.

$this_array= array(
     'string_name' => 'string', 
    'string_array' => array(
        'string_key' => 'string_val'
    )
);

Yes, you will access it by:

$this_array['string_array']['string_key'];
