多维数组中特定值的出现次数

Question

我从mongodb获取数据 我从mongodb得到以下数组作为输出。 现在我尝试了许多PHP脚本来获取devicetype的计数，但没有得到预期的结果

Array
    (
        [0] => Array(
                [_id] => 5774c1c17ffbe048da119681
                [config] => Array(
                        [MOD001] => Array(
                                [devicetype] => modbus
                                [modbusManufacturer] => amit
                                [register_0] => Array
                                    (
                                        [value0] => UPS Power
                                        [location0] => 2
                                    )

                                [register_1] => Array
                                    (
                                        [value1] => Mains Power
                                        [location1] => 2

                                    )
                            )
                        [MOD002] => Array(
                                [devicetype] => modbus
                                [modbusManufacturer] => konsultera
                                [register_0] => Array
                                    (
                                        [value0] => Lobby Temp
                                        [location0] => 22
                                    )

                                [register_1] => Array
                                    (
                                        [value1] => Mains Power
                                        [location1] => 2
                                    )
                            )
                        [NBA001|NBR001|NBE001] => Array
                            (
                                [devicetype] => sensor
                                [zoneNo] => 2                            
                            )
                        [NBA002|NBR002|NBE002] => Array
                            (
                                [devicetype] => sensor
                                [zoneNo] => a                            
                            )
                        [RM001] => Array
                            (
                                [devicetype] => relay    
                                [nodeId] => 001                            
                            )
                        [RM002] => Array
                            (
                                [devicetype] => relay  
                                [nodeId] => 001     
                            )
                    )
            )
    )

现在我需要像下面这样的devicetype modbus 2 继电器2 传感器2

Answer 1

我还没有正确测试过这个，

function multi_array_search($array, $search)
    {
        foreach($array as $key => $value) {
            if (is_array($value)) {
                $sub = multi_array_search($value, $search);
                if (count($sub)) {
                    return $array_occur_count;
                }  
            } 
        }
    }
