I've a php file to export php data to csv.
But I've got the following error
Warning: mysql_num_fields() expects parameter 1 to be resource boolean given in C:\xampp\htdocs\exporttocsv3\export2csv.php on line 28
and
Warning: mysql_fetch_array() expects parameter 1 to be resource boolean given in C:\xampp\htdocs\exporttocsv3\export2csv.php on line 40

$output .= '"'.$heading.'",';
}
$output .="

// Get Records from the table
while ($row = mysql_fetch_array($sql)) {

$output .='"'.$row["$i"].'",';

}
// Download the file
$filename = "myFile.csv";
header('Content-type: application/csv');

As you can see it's in mysql but I'll convert it later to mysqli query. Thank you for future answers
