Question

我有多维数组。

$array = [
    "player" => [
        "@attributes" => [
            "id" => 0,
            "avatar" => "MALE"
        ],
        "scenarios" => [
            "scenario" => [
                0 => [
                    "@attributes" => [
                        "id" => 1,
                        "attempts" => 1,
                        "score" => 7,
                        "completed" => 1,
                        "time" => "00:00:10"
                    ],
                    "badges" => "4,1"
                ],
                1 => [
                    "@attributes" => [
                        "id" => 2,
                        "attempts" => 4,
                        "score" => 0,
                        "completed" => 0,
                        "time" => "00:00:10"
                    ],
                    "badges" => "3, 4"
                ],
                2 => [
                    "@attributes" => [
                        "id" => 3,
                        "attempts" => 2,
                        "score" => 10,
                        "completed" => 0,
                        "time" => "00:00:10"
                    ],
                    "badges" => "2, 2"
                ],
                3 => [
                    "@attributes" => [
                        "id" => 4,
                        "attempts" => 5,
                        "score" => 30,
                        "completed" => 0,
                        "time" => "00:00:10"
                    ],
                    "badges" => "1,1"
                ]
            ]
        ]
    ]
];

我必须将此数据插入数据库。

我试过这段代码

outputValue($array);
          function outputValue($array){

            foreach($array as $key => $value){

              if(is_array($value)){

                  outputValue($value);

                continue;

              }
              else{

                 queryFire($array);

            }

          }
    }      
          function queryFire($array){
              global $id, $attempts, $scores, $time, $lastElement;

               foreach($array as $key => $value){

                switch ($key){
                   case 'id': 
                       $id = $value;
                   case 'attempts':
                        $attempts = $value;
                   case 'score': 
                       $scores = $value;
                   case 'time':
                        $time = $value;

                  }

                }
                   echo $query = "INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('$id', '$attempts', '$scores', '$time')";
echo '<br>';

          }

但它给了我

INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('0', '0', '0', '0')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('0', '0', '0', '0')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('2', '4', '0', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('2', '4', '0', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('2', '4', '0', '00:00:10')
INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('2', '4', '0', '00:00:10')

我不想要...我希望查询执行一次。没有重复。

结果应为

`INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('0', '0', '0', '0')    
    INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('1', '1', '7', '00:00:10')
    INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('2', '4', '0', '00:00:10')

我可以在foreach循环或任何其他技术之外编写查询吗？

Answer 1

我会拿你的数组，然后像这样做一个简单的迭代：

  pdo = Database::connect();

    $sql = 'SELECT orders.animal, orders.size, storage.name, storage.space FROM target LEFT JOIN orders ON storage.name=orders.animal;';
                                foreach ($pdo->query($sql) as $row) {
                                 $count+ = $row['size'];
                                 $result = $row['space'] - $count;
                                 if ($result == 0) {
                                    echo'    
                                  <tr> 
                                    <td>'.$row['name'].'</td>
                                     <td>'.$row['space'].'</td>
                                  </tr>
                                ';
} else {
                                echo'    
                                  <tr> 
                                    <td>'.$row['name'].'</td>
                                     <td>'.$result.'</td>
                                  </tr>
                                ';
                            }
                                Database::disconnect();

<强>结果：

$q = "INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`) VALUES ";
foreach ($array["player"]["scenarios"]["scenario"] as $key => $value) {
    $v = $value["@attributes"];
    $q .= "(`{$v['id']}`, `{$v['completed']}`, `{$v['score']}`, `{$v['attempts']}`),";
}
echo rtrim($q, ',');

Answer 2

试用以下代码。在这里，我试图将字符串附加在变量

中

$查询

单插入。因此DB只能访问一次。

$query = "";    

outputValue($array);
function outputValue($array){

    foreach($array as $key => $value){

        if(is_array($value)){

            outputValue($value);



            continue;

        }else{

            queryFire($array);

        }

    }
}      
function queryFire($array){
    global $id, $attempts, $scores, $time, $lastElement;

    foreach($array as $key => $value){

        switch ($key){
            case 'id': 
            $id = $value;
            case 'attempts':
            $attempts = $value;
            case 'score': 
            $scores = $value;
            case 'time':
            $time = $value;

        }

    }
    if($query=="")
    {
        $query = "INSERT INTO `tbluserscenescores`(`suid`, `completed`, `score`, `attempts`)VALUES('$id', '$attempts', '$scores', '$time')";
    }
    $query .= ",('$id', '$attempts', '$scores', '$time')";


} 
echo $query;

Answer 3

您可以创建查询的第一部分（INSERT INTO tbluserscenescores（suid，completed，score，attempts）VALUES）并添加此项到一个字符串。

然后通过循环追加值以生成单个（尽管是大量的）SQL查询。

<?php

outputValue($array);
          function outputValue($array){

            foreach($array as $key => $value){

              if(is_array($value)){

                  outputValue($value);

                continue;

              }
              else{

                 queryFire($array);

            }

          }
    }      
          function queryFire($array){
              global $id, $attempts, $scores, $time, $lastElement;


              $query = "INSERT INTO `tbluserscenescores`(`suid`,     `completed`, `score`, `attempts`)VALUES";

               foreach($array as $key => $value){

                switch ($key){
                   case 'id': 
                       $id = $value;
                   case 'attempts':
                        $attempts = $value;
                   case 'score': 
                       $scores = $value;
                   case 'time':
                        $time = $value;

                  }

                    $query .= "('$id', '$attempts', '$scores', '$time'),";

                }

            echo $query;

          }   
?>
