Just to make it quicker to create an array.

php array #snippet

// Array with the Teacher class's data | $teacher is the class instantiated
$teacher_Data = #array(
[
	'user_id'       => $teacher->user_id,
	'user_type'     => $teacher->user_type,
	'name'          => $teacher->first_name . ' ' . $teacher->last_name,
	'email_address' => $teacher->email_address
]; #);
