php – 为什么我不能在PDO中使用LOAD DATA LOCAL,即使我可以从cli客户端使用？

我最近将我的Ubuntu 10.04开发服务器升级到了14.04.它实际上是一个全新的安装. PHP版本是5.4.15,现在是PHP 5.5.9. MySQL从5.1.67升至5.5.37.

我试图在新服务器上加载LOCAL DATA INFILE.它使用本地mysql cli客户端运行命令.使用PDO执行时不起作用：

PHP Fatal error:  Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1148 The used command is not allowed with this MySQL version' in /home/ubuntu/mysqltest.php:21
Stack trace:
#0 /home/ubuntu/mysqltest.php(21): PDO->exec('LOAD DATA LOCAL...')
#1 {main}
  thrown in /home/ubuntu/mysqltest.php on line 21

生成错误的代码：

ini_set('mysql.allow_local_infile', 1);
echo "mysql.allow_local_infile: ".ini_get("mysql.allow_local_infile").PHP_EOL;

$options = array(PDO::MYSQL_ATTR_LOCAL_INFILE => 1);
$db = new PDO("mysql:host=$dbHost;dbname=$dbName;charset=utf8", $dbUser, $dbPassword, $options);
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

$db->exec("CREATE TEMPORARY TABLE tmp_table ( id INT(4), col1 varchar(128) ) ENGINE MYISAM");

$loadSQL = <<<'EOT'
LOAD DATA LOCAL INFILE '/tmp/test.csv' INTO TABLE `tmp_table` FIELDS TERMINATED BY ',' OPTIONALLY ENCLOSED BY '"' ESCAPED BY '\\' LINES TERMINATED BY '\n' IGNORE 1 LINES (id, col1)
EOT;

$db->exec($loadSQL);

到目前为止为解决问题采取的步骤：

>我在/etc/mysql/my.cnf的[mysql]和[mysqld]部分添加了local-infile = 1
>我已经检查了mysql.allow_local_infile = On在/etc/php5/cli/php.ini中.
> DB用户是root用户,因此拥有所有权限.
> /tmp/test.csv确实存在,用户拥有完全权限.

解决方法:

这是php中的一个错误.有关说明和解决方法,请参阅https://bugs.php.net/bug.php?id=68226.
