Question

I am new to PHP OOP and I am having problem getting arrays back.

class example
{
    public $array;

    public function __construct()
    {
        $this->array = array();

    }

    public function do_work()
    {
        $this->array[] = 'test';
    }
}
$test = new example();
$test->do_work();
$test->array;

I keep getting a empty array instead of ‘test’.
What am I doing wrong?

Answer 1

This is because you never actually call the function $test->do_work(); The constructor just creates the empty array, and then you attempt to access the property. It should be empty.

Updates

I see you updated your question. If you simply echo $test->array, it should just print Array. However, when I copy your updated code and perform a var_dump($test->array), this is the output I get:

array(1) { [0]=> string(4) "test" } 

Which I believe is what you are expecting. The code that you have in your question, though, should output nothing. You are doing nothing with $test->array, the variable is being evaluated and then thrown away.
