大家好，我已经问过一个有关基于数组的键等于数组中的值的问题。 这是我之前的链接，请检查输入链接描述 here
如果我遵循上述链接，则无法获取正确的数据。 in_array查找所有列，但我想在room_no中找到数组中只有一列。 如果我使用in_array（1，$ singleArray）它将找到数组中的所有列，我只需要key是room_no等于1。

如果您在数组[room_no]中发现了该数组[0]中2次的上述输出，则为数组1。如果我使用in_array(1,$myArrayOutPut){ }，它将使用array [3]，array [4]状态键也为1。因此，将键为1的所有数组都作为键，但是我需要room_no为1
答案 0 :(得分：0)
Kindly see below code to access multidimensional array with for each loop and subsequently check the elements with switch case. :
$passenger_info = array(0=> array("room_no"=>1,"passenger_type"=>"adult"), 1=>array("room_no"=>1,"passenger_type"=>"children"), 2=> array("room_no"=>1,"passenger_type"=>"adult"), 3=> array("room_no"=>2,"passenger_type"=>"children"), 4=> array("room_no"=>2,"passenger_type"=>"adult"));
echo "<pre>";
print_r($passenger_info);
echo "</pre>";
echo "<hr>";
$selected_room = 2;
$adult_count = 0;
$child_count = 0;
foreach($passenger_info as $key => $value) {
if($value["room_no"] == $selected_room){
switch ($value["passenger_type"]){
case "adult":
$adult_count++;
break;
case "children":
$child_count++;
break;
default:
break;
}
}
}
echo "Adults : ".$adult_count;
echo "<br>";
echo "Children : ".$child_count;
