1. 建表語句

$createTable = " CREATE TABLE `user` (
  `uid` int(10) unsigned NOT NULL AUTO_INCREMENT COMMENT '自增id',
  `addtime` int(11) unsigned DEFAULT '0' COMMENT '添加時間戳',
  `status` tinyint(4) NOT NULL DEFAULT '0',
  `username` varchar(20) NOT NULL DEFAULT '' COMMENT '用戶名',
  `mobile` varchar(11) NOT NULL DEFAULT '' COMMENT '手機號',
  `email` varchar(50) NOT NULL DEFAULT '',
  `password` varchar(64) NOT NULL DEFAULT '' COMMENT '密碼',
  `reg_from` varchar(20) NOT NULL DEFAULT '' COMMENT '注冊來源',
  `unid` char(32) NOT NULL DEFAULT '',
  `add_time` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
  PRIMARY KEY (`uid`),
  KEY `username` (`username`)
) ENGINE=InnoDB AUTO_INCREMENT=262 DEFAULT CHARSET=utf8;";


$createTable = str_replace('`', '', $createTable);
$createTable = preg_replace('/COMMENT.*,/U', ',', $createTable);
$createTable = preg_replace("/\'(\d+)\'/U", '$1', $createTable);
$createTable = preg_replace("/AUTO_INCREMENT=\d+/", '', $createTable);
$createTable = preg_replace("/KEY\s+[a-z0-9]+\s\(.*\)/i", '', $createTable);

$createTable = str_replace(['unsigned', 'ENGINE=InnoDB', 'DEFAULT CHARSET=utf8', 'AUTO_INCREMENT'], [''], $createTable);


echo $createTable;
echo '<pre>';
