PHP实现快速向MySQL插入千万条数据

$host = 'localhost';
$dbname = 'your_database';
$user = 'your_username';
$password = 'your_password';
try {
    $pdo = new PDO("mysql:host=$host;dbname=$dbname", $user, $password);
} catch (PDOException $e) {
    die("Error: " . $e->getMessage());
}

$data = []; // 你的数据数组
$sql = "INSERT INTO your_table (column1, column2) VALUES (?, ?)";
$stmt = $pdo->prepare($sql);
foreach ($data as $row) {
    $stmt->execute([$row['column1'], $row['column2']]);
}

try {
    $pdo->beginTransaction();
    foreach ($data as $row) {
        $stmt->execute([$row['column1'], $row['column2']]);
    }
    $pdo->commit();
} catch (PDOException $e) {
    $pdo->rollBack();
    die("Error: " . $e->getMessage());
}

# 在MySQL配置文件中
max_allowed_packet = 256M
innodb_buffer_pool_size = 512M

$sql = "LOAD DATA LOCAL INFILE 'path/to/your/file.csv' INTO TABLE your_table FIELDS TERMINATED BY ','";
$pdo->exec($sql);
