php - 访问数组中的 JSON

Question

以下数组中包含 JSON:

$row['modifiers']

如何访问其中的 modifier_value？

我试过:

$row['modifiers']['modifier_value'];

这是数组的样子:

[{"modifier_id":"","modifier_name":"Type","modifier_type":"custom","modifier_value":"Tour","option_id":"","price_mod":"","price_mod_inc_tax":""}]

Answer 1

这样试试

    <?php

    $a = '[{"modifier_id":"","modifier_name":"Type","modifier_type":"custom","modifier_value":"Tour","option_id":"","price_mod":"","price_mod_inc_tax":""}]';

    $decode = json_decode($a);

    foreach ($decode as $arr){
        echo $arr->modifier_name;
        echo $arr->modifier_type;
        // so on
    }

?>
