php - 如何在 PHP 中转义 mysqli_query() 中的双引号字符？

Question

我正在尝试使用 CSV 文件更新 mysql 数据库。

我有这个查询在 phpmyadmin 中工作

LOAD DATA INFILE 'C:/wamp/www/website/test_mysql_import.csv' INTO TABLE `csv_preset` FIELDS TERMINATED BY ',' ENCLOSED BY '"' ESCAPED BY '"' LINES TERMINATED BY '\n'    

但是当我尝试在 mysqli_query 函数中使用它时，它不会更新数据库。

这是完整的代码块:

<?php require "db_connect.php"; ?>    
    <?php
    $csv_file = "C:/wamp/www/website/test_mysql_import.csv";

    $sql_dump ="TRUNCATE TABLE csv_preset";
    $sql_update = "LOAD DATA INFILE '$csv_file' INTO TABLE `csv_preset` FIELDS TERMINATED BY ',' ENCLOSED BY '"' ESCAPED BY '"' LINES TERMINATED BY '\n'");
    mysqli_query($db_conx, $sql_dump);
    mysqli_query($db_conx, $sql_update);
?>

<?php require "db_connect.php"; ?>    
    <?php
    $csv_file = "C:/wamp/www/website/test_mysql_import.csv";

    $sql_dump ="TRUNCATE TABLE csv_preset";
    $sql_update = "LOAD DATA INFILE '".$csv_file."' INTO TABLE `csv_preset` FIELDS TERMINATED BY ',' ENCLOSED BY '\"' ESCAPED BY '\"' LINES TERMINATED BY '\n'");
    mysqli_query($db_conx, $sql_dump);
    mysqli_query($db_conx, $sql_update);
?>
