mysql_fetch_array()/mysql_fetch_assoc()/mysql_fetch_row()/mysql_num_rows etc… expects parameter 1 to be resource

Question

I am trying to select data from a MySQL table, but I get one of the following error messages:

mysql_fetch_array() expects parameter 1 to be resource,

Answer 1

$query = "SELECT Name,Mobile,Website,Rating FROM grand_table order by 4";

while( $data = mysql_fetch_array($query))
{
    echo("$data[0]$data[1]$data[2]$data[3]");      
}

Instead of using a WHERE query, you can use this ORDER BY query. It's far better than this for use of a query.

I have done this query and am getting no errors like parameter or boolean.
