如何搜索数组并获取它的“=>”值？

Question

I have an input:

$url = $params[0];

I have an array:

$dictionary = array(
    "stock" => 1,
    "user" => 2,
    "zone" => 3);

How can I use the input to search the left values of this array (stock, user, zone, etc.) and get back the value on the right (1, 2, 3, etc.)?

Answer 1

Pretty simple, just access it like this

$dictionary[$url]
