reading Associative array

Question

I have the following array...generated from this code.

$aa = new_Arr();

print_r($aa);   //here is the result...


     cl_aa Object
    (
        [data:cl_aa:private] => Array
            (
                [t_a] => Array
                    (
                        [0] => Array
                            (
                                [f_c] => LAL
                                [p_r] => RN
                                [id] => 1214125
                                [gender] => m
                            )
                    )

                [t_b] => Array
                    (
                    )

                [t_l] => Array
                    (
                        [0] => Array
                            (
                                [p_lev] => 2
                                [p_date] => 
                                [p_r] => 
                            )
                    )

                [t_r] => Array
                    (
                        [0] => Array
                            (
                                [I_r] => 19
                            )

                    )

            )

        [db:cl_aa:private] => PDOTester Object
            (
            )
    )

I try to read it as like this...

foreach ($aa as $key=>$value) {
     print_r($key);
     echo "<h1>". $value['bb']. "</h1>";
 }

but no result i can see...

how do I read the above array? Help please?

If your objects are private, you can't access them from outside their class without getters. — BMN

Either make them public or create getters in your class. I suggest you have a look at php.net/manual/en/language.oop5.php — BMN

The difference with getters would be that the values cannot be changed outside of the given class (without any setters). Decision between public and getters will be based on your particular case. — Menno

there is no way to change from private to public, some other idea please? — Mr Internet

Provide your cl_aa class some getters :

public class cl_aa {

    private $data;
    private $db;

    public function getData() {
        return $this->data;
    }
    public function getDb() {
        return $this->db;
    }
}

And to access your data from outside :

$aa = new_Arr(); // I assume this function returns a cl_aa object.
print_r($aa->getData());
print_r($aa->getDb());
