Hi friends. I wanted to open a help topic for friends who research PDO.
In this context, we find the number of data of the table in the database using PDO.
Let's connect the database first.
Here we have selected a table and we want to know how many data we select in this table.
I leave it blank because I will not enter an ID value or want any information.
Finally we will use it now. fetchColumn(); We want to shoot them all using the codes as follows;
Now we have entered our php query and we want to know the number of users immediately. So let's suppress our value with echo.

try {
$db = new PDO('mysql:host=localhost;dbname=DBNAME','root','');
} catch (PDOException $e) {
echo $e->getMessage();
}

PHP:
$userscount = $db->prepare('SELECT COUNT(*) FROM users');
I leave it blank because I will not enter an ID value or want any information.
PHP:
$userscount->execute();

$alluserscount = $userscount->fetchColumn();

echo $alluserscount
