如何打印mysql_num_rows？

Question

i have a database structure like this

and am trying to print the rows count but am getting 1 only

the code am using is

$sql="select Count(*) from uniqueviews where hour=13"; $result=mysql_query($sql); $ml=mysql_num_rows($result); echo $ml;

according to the query it should print 6 but its printing 1

where am doing wrong ?

i think its counting the rows ?

how can i print the result after rows count ?

Answer 1

Count(*) only returns one row, containing the number of rows. That's why you get only 1 as return value. If you want the actual value, you can either do this:

$sql="select * from uniqueviews where hour=13"; 
$result=mysql_query($sql); 
$ml=mysql_num_rows($result); 
echo $ml;

or this:

$sql="select COUNT(*) from uniqueviews where hour=13"; 
$result=mysql_query($sql);  
$row = mysql_fetch_array($result, MYSQL_NUM);
$ml=$row[0];
echo $ml;
