当我使用0作为主键时，重复行将插入表中

Question

When i use this SQL command, duplicate rows will insert.

SQL command is:

$dbh = mysql_connect(db_host, db_user, db_pass);
mysql_select_db(db_name, $dbh);

mysql_query("INSERT INTO test VALUES(0, '1')");

this happened just when i use 0 for first field that is primary and auto_increment

Strangely the problem was firefox browser cache!
I just tried to reset firefox in safe mode and the problem is solved now.
