php putting an array from _construct into function

Question

II'm using an API and was wondering why I am having trouble getting an array to cross into a function. The following works fine but how can I make it work for an array.

public function __construct()
{
    parent::__construct(); // Init parent constructor
    $this->dbConnect();
    $this->test();
}

public function test()
{
    $this->category = "bracelets";

}

private function piece()
{
    // Pass an array into this function here and then use depending on array key
    $cat = $this->category;
}

So instead of a constant $this->category="bracelets. I would like this to be an array. e.g.

public function test()
{
        $array = [
         "foo" => "bar",
         "bar" => "foo",
        ];
        $this->category = $array;

}

Ok, this has been resolved. It was due to a minor error elsewhere. For a moment I believed there was an issue with arrays in a restful API.

I hope this is useful to any others who wish to pass one function results to another in an api class.

Arrays should work the same way as strings here. There's no additional "trick" to assign an array to a property and use it from there. It's unclear what your issue is. — deceze, Mar 04 '15 at 10:17

Looking at you code, it seems you want the category property to be an array of all categories, read from the database..?

I did spot some bugs in your code:

You have variable name mixups on $cat_array vs. $cat_arr
You select cat column from DB but try read category

I have made slight changes in your test() method to fix it:

public function __construct()
{
    parent::__construct(); // Init parent constructor
    $this->dbConnect();
    $this->test();
}

// Array with name of all categories, indexed by category id
private $category;

public function test()
{
    $query = "SELECT c.id, c.cat FROM category c order by c.id asc";
    $cat = $this->mysqli->query($query)
        or die ($this->mysqli->error . __LINE__);

    if ($cat->num_rows > 0) {
        $cat_array = array();
        while ($crow = $cat->fetch_assoc()) {
            $id = $crow['id'];
            $cat_array[$id] = $crow['cat'];
            //$cat_array[$crow['id']]=$crow['category'];
        }
        $this->category = $cat_array;
        //$this->response($this->json($result), 200); // send  details
    }
}

private function piece()
{
    // Pass an array into this function here and then use depending on array key
    $cat = $this->category;

    // Check if it is working as expected
    print_r($cat);
}
