php - 使用指定值 php 获取特定对象集

Question

再会！我有一个关于从对象（Php Laravel）中的数组中检索特定对象的问题。比如说

这是我要检索的数据：

$variable = [array];
// This is the result whenever I use this on blade to see the result of the variable. 
json_encode($variable, true); 

//result 
   [
     {"0":{
           "id":1,
           "name":"Joe",
           "year":2012,
          },
     }, 
     {"0": 
          {
           "id":2,
           "name":"Mark",
           "year" : 2020,
          }
     }, 
     {"0": 
          {
           "id":2,
           "name":"Mark",
           "year" : 2020,
          }
     }

   ]

我想使用 php 检索具有 year = 2020 和 id = 2 的项目并将其插入到新变量中。

所以我期望结果是：

  [ 
    { 
     "0": 
          {
           "id":2,
           "name":"Mark",
           "year" : 2020,
          } 
    },
   {"0": 
          {
           "id":2,
           "name":"Mark",
           "year" : 2020,
          }
     }
   ]

我试过了 ：

  $new_val = []
  foreach($variable as $key => value) {
     if($value['year'] == "2020" && $value['id'] == "2") {
         array_push($new_val , $variable[$key]):
     }
  }

Answer 1

$variable[] = [
    "id"   => 1,
    "name" => "Joe",
    "year" => 2012,
];
$variable[] = [
    "id"   => 2,
    "name" => "Mark",
    "year" => 2020,
];

function _search($array, $name, $year)
{
    foreach ($array as $item) {
        if ($item['name'] == $name && $item['year'] == $year) {
            return $item;
        }
    }
    return false;
}
$new = _search($variable, 'Mark', '2020');
print_r($new);````
