我在这条线上看到这个错误：
mysql_query('SELECT * FROM keys WHERE left > 0');

Answer 1

两个字段keys和left都是mysql reserved word所以您必须像这样使用backticks

mysql_query('SELECT * FROM `keys` WHERE `left` > 0');

最好用 trigger_error和 mysql_error来写。这将产生实际的mysql错误（如果有的话）

mysql_query('SELECT * FROM `keys` WHERE `left` > 0') or trigger_error(mysql_error());
