使用PHP腳本將CSV導入到MySQL？

Question

我有一個CSV文件，我想要導入到數據庫中，然後使用省略的列導出相同的數據。我會如何去做這件事？有什麼建議麼？

<?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"; 

?>
