مشکل mysql_fetch_array() expects parameter

[mhm233]

سلام

من یه اسکریپت دارم که قبلا روی وی پی اس لینوکس و هاست بخوبی کار میکرد! اما الان روی ویندوز زدم ولی ارور میده :

PHP Warning: mysql_fetch_array() expects parameter 1 to be resource, boolean given in C:\Inetpub
\vhosts\***\site1\lib\mysql.php on line 30



این هم صفحه mysql.php :

بعد از دستور mysql_query دستور or die(mysql_error()); بذارید تا خطا مشخص بشه
