Php多维数组从具有不同键的数组中获取值

Question

我需要帮助。我有一个数组：

$A = 
    array(
        "0" =>
            array(
                "1" => array('name' => '1234', 'value' => '1'),
                "2" => array('name' => '5678', 'value' => '8')
            ),
        "1" =>
            array(
                "1" => array('name' => '5678', 'value' => '5')
            )
    );

如果数组键value值为name，如何从数组中获取5678（在foreach循环中）？

Answer 1

希望这会有所帮助

foreach ($A as $B) {
 foreach ($B as $C) {
    if ($C['name'] == '5678') {
       echo $C['value'].'<br>';
    }
  }
}

Answer 2

您可以这样做：

foreach ($A as $array_item) {
  foreach ($array_item as $inner_array) {
      if ($inner_array['name'] == '5678') {
          var_dump($inner_array['value']);
      }   
  }   
}
