php上传mysl数据

Question

<?php

$conn = new mysqli('localhost', 'tbhaidian', '123456', 'tbhaidian');

// 检查连接是否成功
if ($conn->connect_error) {
    die("连接失败: " . $conn->connect_error);
}

// 读取CSV文件内容
$csv = file_get_contents('789.csv');

// 将CSV文件内容转换为SQL语句
$sql = "LOAD DATA INFILE '789.csv' INTO TABLE ceshi FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 ROWS";

// 执行SQL语句
$result = mysqli_query($conn, $sql);

// 检查执行结果
if ($result) {
    echo "导入成功";
} else {
    echo "导入失败: " . mysqli_error($conn);
}

// 关闭数据库连接
mysqli_close($conn);

?>

报错 导入失败: Access denied for user 'tbhaidian'@'localhost' (using password: YES)
这个是什么原因。账号密码是对的啊

Answer 1

csv文件转物理路径试试，而且确认mysql服务器和php web服务器是同一台电脑，要不找不到文件

$sql = "LOAD DATA INFILE '".realpath('789.csv')."' INTO TABLE ceshi FIELDS TERMINATED BY ',' ENCLOSED BY '\"' LINES TERMINATED BY '\r\n' IGNORE 1 ROWS";

不行就用上面读出的内容组成成多条insert into sql语句来执行
