从 PHP 中加载.sql文件

$db = new PDO($dsn, $user, $password);

$sql = file_get_contents('file.sql');

$qr = $db->exec($sql);

phpBB使用一些函数来解析他们的文件。它们的评论相当好（这是一个例外！），所以你可以很容易地知道他们做了什么（我从 http://www.frihost.com/forums/vt-8194.html 那里得到了这个解决方案）。这是我经常使用的解决方案：

<?php
ini_set('memory_limit', '5120M');
set_time_limit ( 0 );
