php - 从数组中插入多行到数据库

Question

我需要一些帮助来将来自不同数组的多行插入到我的数据库中。

我正在为座位计划制作数据库，每个座位 block 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_numbers，为每个 seat_block 添加 5 个 seat_row。

我用一些 foreach 循环模拟了它，但需要一些帮助将它变成一个(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？我只想避免编写超过 100 行的 SQL 语句；)

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

尝试

<?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);



?>
