Row count with PDO

Question

There are many conflicting statements around. What is the best way to get the row count using PDO in PHP? Before using PDO, I just simply used mysql_num_rows.

Answer 1

There is a simple solution. If you use PDO connect to your DB like this:

try {
    $handler = new PDO('mysql:host=localhost;dbname=name_of_your_db', 'your_login', 'your_password'); 
    $handler -> setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} 
    catch (PDOException $e) {   
    echo $e->getMessage();
}

Then, the query to DB will be:

$query = $handler->query("SELECT id FROM your_table WHERE ...");

And finally, to count the rows matching your query write like this

$amountOfRows = $query->rowcount();
