MySQL: why does "SELECT count()" return a value of array?

There are two solution to get total number of records from any table, Here are both explain in brief:

First one is - you can used COUNT() directly to select query like below e.g.

$Qr=mysql_query('select COUNT(*) from tablename');
$Qry=mysql_fetch_array($Qr);
echo $Qry;

It's display total number of records.

--------------------------


Second one is - 'mysql_num_rows' like below e.g.

$Qr=mysql_query('select * from tablename');
$Qry=mysql_num_rows($Qr);
echo $Qry;

It's display total number of records.



Enjoy!
