Question

I’m sure this has been asked before, but I can’t seem to find the answer.

To that end, I have an array that looks like this:

Array
(
    [0] => Array
        (
            [status] => active
            [sid] => 1
        )

    [1] => Array
        (
            [status] => expired
            [sid] => 2
        )

)

What I’d like to be able to do is type $arrayName[“active”] and it return the SID code. I will be using this like a dictionary object of sorts. It’s like I need to reindex the array so that it is the key/value pair that I need. I was just wondering if there was an easier way to do it.

Answer 1

You should convert your nested arrays into a single associative array. Something like this should take your example and turn it into an associative array:

$assoc_array = array();
foreach( $example_array as $values ) {
  $assoc_array[$values["status"]] = $values["sid"];
}

You can then access the sid for a given status by using $assoc_array["expired"] (returns 2)
