快速搜索PHP数组

Question

I have an array with around 3500 array items inside it, the format being below. I have two dynamic variables that change and I need to search the array to find out row price_value based on already knowing price_slot and country.

I've currently got the below but this is taking too long. Is there anyway I can speed up this access?

PHP Function

$country = US;
$priceSlot = 3;
$priceValue = getPriceValue($priceSlot, $country);


function getPriceValue($priceSlot, $country) {
    // Search in array for price
    foreach ($array as $arrayItem) {
        if ($arrayItem['price_slot'] == $priceSlot && $arrayItem['country'] == $country) {
            return $arrayItem['price_value'];
        }
    }
    return null;
}

Snippet of Array

Array
(
    [0] => Array
        (
            [price_slot] => 1
            [base_price] => Get in Touch
            [country] => US
            [price_multiplier] => 
            [price_value] => Get in Touch
        )

    [1] => Array
        (
            [price_slot] => 2
            [base_price] => 9000
            [country] => US
            [price_multiplier] => 1.3
            [price_value] => 11700
        )

    [2] => Array
        (
            [price_slot] => 3
            [base_price] => 12000
            [country] => US
            [price_multiplier] => 1.3
            [price_value] => 15600
        )

    [3] => Array
        (
            [price_slot] => 4
            [base_price] => 15000
            [country] => US
            [price_multiplier] => 1.3
            [price_value] => 19500
        )

    [4] => Array
        (
            [price_slot] => 5
            [base_price] => 4000
            [country] => US
            [price_multiplier] => 1.3
            [price_value] => 5200
        )

    [5] => Array
        (
            [price_slot] => 6
            [base_price] => 1600
            [country] => US
            [price_multiplier] => 1.3
            [price_value] => 2080
        )

Is there any faster way to get around this?

Thanks!

Answer 1

I'm still trying to think of another way, but this is faster:

$result = array_filter($array, function($v) use($priceSlot, $country) {
                                   return ($v['price_slot'] == $priceSlot && 
                                           $v['country']    == $country);
                               });

Then you would need to access:

echo current($result)['price_value'];

You can get the price_value in $result like this:

array_filter($array, function($v) use(&$result, $priceSlot, $country) {
                         $result = ($v['price_slot'] == $priceSlot &&
                                    $v['country']    == $country) ?
                                    $v['price_value'] : null;
                     });
