How to use MySQL Found_Rows() in PHP?

Question

I try to avoid doing Count() because of performance issue. (i.e. SELECT COUNT() FROM Users)

If I run the followings in phpMyAdmin, it is ok:

Answer 1

This is an easy way & works for me :

$query = "
SELECT SQL_CALC_FOUND_ROWS * 
FROM tb1
LIMIT 5";

$result = mysqli_query($link, $query);

$query = "SELECT FOUND_ROWS() AS count";
$result2 = mysqli_query($link, $query);

$row = mysqli_fetch_array($result2);

echo $row['count'];
