Question

I’m a bit perplexed with this code. $this->product is an Object with 12 vars. The var_dump indicates that $key is a string.

foreach ($this->product as $key => $val) {
    if (($key !== "id") || ($key !== "weight")) {
        var_dump($key);
    } else {
        print_r("Success" . $key);
    }
}

Despite “id” and “weight” being present as var names and represented as strings within $key they are not caught with this conditional. Does anyone have any ideas?

I think you meant to do:

foreach ($this->product as $key => $val) {
    if (($key !== "id") && ($key !== "weight")) {
        var_dump($key);
    } else {
        print_r("Success" . $key);
    }
}

(($key !== "id") || ($key !== "weight")) is always true, $key can’t be “id” and “weight” at the same time.
