why does mysql_fetch_array() expect parameter 1 to be resource? why isn't parameter 1 resource?

Question

Warning: mysql_fetch_array() expects parameter 1 to be resource, string given in C:\\xampp\\htdocs\\test\\index.php on line 19

Answer 1

Your parameter to mysql_fetch_array() function is your SQL statement string. This is what your warning say. You should first use $res = mysql_query($sql); and pass $res as parameter to mysql_fetch_array()
