How can I print out a single field in my multidimensional array?

So I do a print for my object: print_r ($objMailer);

And I get the following below:

mymailer Object
(
[_strRecipient:mymailer:private] => 
[_strBcc:mymailer:private] => 
[_strSubject:mymailer:private] => 
[_strEmail:mymailer:private] => 
[_arrData:mymailer:private] => Array
(
    [full_name] => brian
    [invitee_name] => test
    [email] => [email protected]
    [captcha] => kqd2q9
)

[_arrAttachments:mymailer:private] => 
[_blnCaptcha:mymailer:private] => 1
[_arrErrors:mymailer:private] => Array
(
)

)

I need to echo/print out just the 'full_name' field? How can I go about doing this?

The object you are referencing has an _arrData member variable which has private scope resolution, which means you cannot access it from outside the class. Chances are there is a public accessor which will allow you get the information you are after, but no way to tell unless you introspect the object itself.

I would suggest doing something like:

foreach (get_class_methods($mymailer) as $method) { echo 'M: ' . $method . '<br>'; } exit;

Then you can see the methods available to you, chances are there is a getData() method, with which you can do this:

$mailerData = $mymailer->getData();

var_dump($mailerData['full_name']);

There may even be a method to get the full name, something like this:

var_dump($mymailer->getFullname());

You can not trivially. As the print_r output shows that is within a private member.

You can either provide it from within your (?) mymailer object:

return $this->_arrData['full_name'];

or by using Reflection to make it accessible from the outside:

$refObj  = new ReflectionObject($objMailer);
$refProp = $refObj->getProperty('_arrData');
$array   = $refProp->getValue($objMailer);

echo $array['full_name'];

Since it's private you'll need to use a getter

If you want to echo the value inside a method of mymailer class, you may use:

echo $this->_arrData['full_name'];
