PHP：在一列中搜索多维数组

  • 772

有一个多维关联数组$array：

Array (
  [0] => Array ( [amount] => 100 [currency] => 643 )
  [1] => Array ( [amount] => 200 [currency] => 643 )
  [2] => Array ( [amount] => 300 [currency] => 643 )
  [3] => Array ( [amount] => 400 [currency] => 643 )
)

请告诉我如何在 PHP 中检查键是否在此数组中有amount值100？

    $exists = (array_search(100, array_column($data, 'amount')) !== false);
