Question

我有这个对象数组$ work_breaks（Var_dump）：

array(2) {
  [0]=>
  object(stdClass)#3717 (7) {
    ["ID"]=>
    string(1) "7"
    ["location"]=>
    string(1) "0"
    ["service"]=>
    string(1) "0"
    ["worker"]=>
    string(1) "3"
    ["status"]=>
    string(4) "open"
    ["hours"]=>
    string(624) "a:7:{s:6:"Sunday";a:3:{s:6:"active";s:2:"no";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}s:6:"Monday";a:3:{s:6:"active";s:2:"no";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}s:7:"Tuesday";a:3:{s:6:"active";s:2:"no";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}s:9:"Wednesday";a:3:{s:6:"active";s:3:"yes";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}s:8:"Thursday";a:3:{s:6:"active";s:2:"no";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}s:6:"Friday";a:3:{s:6:"active";s:2:"no";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}s:8:"Saturday";a:3:{s:6:"active";s:2:"no";s:5:"start";s:5:"00:00";s:3:"end";s:5:"00:30";}}"
    ["note"]=>
    string(0) ""
  }
  [1]=>
  object(stdClass)#3935 (7) {
    ["ID"]=>
    string(1) "8"
    ["location"]=>
    string(1) "0"
    ["service"]=>
    string(1) "0"
    ["worker"]=>
    string(1) "3"
    ["status"]=>
    string(6) "closed"
    ["hours"]=>
    string(37) "a:1:{s:16:"exceptional_days";s:0:"";}"
    ["note"]=>
    string(0) ""
  }
}

我试图用[hours]替换序列化数组，其中[status] = open，使用新的seralised数组$ newSchedule：

$work_breaks['hours'] = $newTimes;

但我似乎无法让它发挥作用。如果[状态]打开＆＃39;？

，我该如何进行有条件检查

由于每个数组项都是stdClass个对象，因此您应该使用->而不是方括号。

foreach ($work_breaks as $item) {
    if ($item->status == 'open') {
        // do something
        $item->hours = 'Your value';
    }
}

PHP：对象数组 - 替换键和值
