<?php
    $databasehost = "localhost"; 
    $databasename = "test"; 
    $databasetable = "sample"; 
    $databaseusername="test"; 
    $databasepassword = ""; 
    $fieldseparator = ","; 
    $lineseparator = "\n";
    $csvfile = "filename.csv";

        if(!file_exists($csvfile)) {
            die("File not found. Make sure you specified the correct path.");
        }

try {
    $pdo = new PDO("mysql:host=$databasehost;dbname=$databasename", 
    $databaseusername, $databasepassword,
    array(
        PDO::MYSQL_ATTR_LOCAL_INFILE => true,
        PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION
        )
    );
} catch (PDOException $e) {
die("database connection failed: ".$e->getMessage());
}

$affectedRows = $pdo->exec("
    LOAD DATA LOCAL INFILE ".$pdo->quote($csvfile)." INTO TABLE `$databasetable`
      FIELDS TERMINATED BY ".$pdo->quote($fieldseparator)."
      LINES TERMINATED BY ".$pdo->quote($lineseparator));

echo "Loaded a total of $affectedRows records from this csv file.\n";

?>

使用PHP脚本将CSV导入MySQL？
