$row = mysql_fetch_array($result, MYSQL_NUM); 
echo $row[1];   

print_r($row); is displaying no of records but whu echo is not working

Answer 1

You need mysql_num_rows

echo mysql_num_rows($result);

That’ll give you number of rows return from query.

If, however, you are using the count keyword in your query, you should modify your code like this:

$sql = "select count(userId) as total from tblUser";
$result = mysql_query($sql) or die(mysql_error());
$row = mysql_fetch_assoc($result);
echo $row['total'];

Update:
You can also count total users like this:

$sql = "select userId from tblUser";
$result = mysql_query($sql) or die(mysql_error());
echo mysql_num_rows($result);
