从数组中将多行插入数据库答案

【问题标题】：insert multiple rows into database from arrays从数组中将多行插入数据库

【问题描述】：

我需要一些帮助，将不同数组中的多行插入到我的数据库中。

我正在为座位计划创建数据库，每个座位区有 5 排 (A-E)，每排有 15 个座位。

我的数据库行是seat_id、seat_block、seat_row、seat_number，因此我需要为每个seat_row 添加15 个seat_number，为每个seat_block 添加5 个seat_rows。

我用一些 foreach 循环对其进行了模拟，但需要一些帮助才能将其转换为（希望是单个）SQL 语句。

$blocks = array("A","B","C","D");
$seat_rows = array("A","B","C","D","E");
$seat_nums = array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15");

foreach($blocks as $block){

    echo "<br><br>";
    echo "Block: " . $block . " - ";

    foreach($seat_rows as $rows){

        echo "Row: " . $rows . ", ";

        foreach($seat_nums as $seats){
            echo "seat:" . $seats . " ";
        }

    }
}

也许有更好的方法来代替使用数组？我只是想避免编写超过 100 行的 SQL 语句；）

（如果有人知道 CI 的特定方法，我也使用 codeigniter，但我不太在意）

你有没有想过使用ENUMs，一个用于block、row和num？

【解决方案1】：

试试

<?php

    $blocks = array("A","B","C","D");
    $seat_rows = array("A","B","C","D","E");
    $seat_nums = array("1","2","3","4","5","6","7","8","9","10","11","12","13","14","15");

    foreach($blocks as $block){
        foreach($seat_rows as $rows){
            foreach($seat_nums as $seats){
                $querys[] = "('" . $block "','" . $rows . "', '" . $seats . "' )";
            }
        }
    }

    $query_inserts = join ( ", ", $querys );

    $query = "
        INSERT INTO
            table
        ( block, rows, seats )
        VALUES
            " . $query_inserts . "
        ";

    mysql_query ($query);



?>

【解决方案2】：

一种解决方案是使用准备好的语句：

$pdo = new PDO('mysql:dbname=mydb', 'myuser', 'mypass');

$stmt = $pdo->prepare('INSERT INTO seats 
                          (seat_id, seat_block, seat_row, seat_number)
                          VALUES (?,?,?,?);
                     ');

foreach (...) {
   $stmt->execute(array($seat_id, $seat_block, $seat_row, $seat_number));
}
