Question

I have this array

Array
(
    [name] => Step1 is here
    [standard] => Array
        (
            [product_id] => 85,99
            [product_name] => Step1 is here
            [product_price] => 976.0000
            [product_description] => :something 
            [product_image] => http://someurl.com/shop_pos/image/data/13D.png
        )

    [professional] => Array
        (
            [product_id] => 61
            [product_name] => Step1 is here
            [product_price] => 289.0000
            [product_description] => somethingothere 
            [product_image] => http://someurl.com/shop_pos/image/data/13B.png
        )
    [premium] => Array
        (
            [product_id] => 677
            [product_name] => Step1 is here
            [product_price] => 289.0000
            [product_description] => somethingothere 
            [product_image] => http://someurl.com/shop_pos/image/data/13A.png
        )

)

Is there an easy of referencing in the proper order that i need. SO the order i need is standard, professional, premium.. so if one is not present can I do to the other like this

 if (!isset($my_array['standard'])) {
 $use_me = $my_array['standard']
}elseif(!isset($my_array['professional'])) {
 $use_me = $my_array['professional']
}elseif(!isset($my_array['professional'])) {
    $use_me = $my_array['premium']}
}

i have the above code that i think may work but is there a better way

Answer 1

I would do this:

foreach (array('standard', 'professional', 'premium') as $name) {
    if (isset($my_array[$name])) {
        $use_me = $my_array[$name];
        break;
    }
}

or a little more structured:

function selectPlan($array) {
    foreach (array('standard', 'professional', 'premium') as $name) {
        if (isset($array[$name])) return $array[$name];
    }
}

$use_me = selectPlan($my_array);
