php获取多维数组值

Question

I have an array that looks like this:

'application_noreply_email' => array(
    'name' => 'example.com',
    'host' => 'smtp.gmail.com',
    'connection_class' => 'login',
    'port' => '587',
    'connection_config' => array(
        'ssl' => 'tls',
        'username' => '[e-mail]',
        'password' => 'pass',
    ),
), 

How can i get the value of username?

I have tried using it like this, as you suggeste but it doesnt work.

$config['application_noreply_email']['username']

but this works in different situations $config['application_noreply_email']

Answer 1

Just a series of bracketed key names:

$application_noreply_email['connection_config']['username']

From the way you formatted your question, it looks like application_noreply_email may be a key in a larger array, in which case you would do this:

$theArrayVariableName['application_noreply_email']['connection_config']['username']
