$DB->setFetchMode($fetchMode);

// Exemple
$DB->setFetchMode(PDO::FETCH_ASSOC);

See the list of all available modes

Request (waiting for data)

// @param $request string SQL query
// @param array|null $values Optional values
// @param bool $all Query with several rows or not (Default true)
// @return array|mixed Return
$values = $DB->fetch($request, $values = null, $all = true);

// Example 1
$values = $DB->fetch("SELECT username, firstname, lastname, email FROM users"); // Return several rows

// Example 2
$age = 21; // We want only adults
$values = $DB->fetch("SELECT username, firstname, lastname, email FROM users WHERE age >= ?", [$age]); // Return several rows of adults

// Example 3
$firstname = "John";
$lastname = "Doe";
$age = 21;
$values = $DB->fetch("SELECT username, firstname, lastname, email FROM users WHERE age >= ?", [$firstname, $lastname, $age], false); // Return ONLY one row with filters (firstname, lastname et age)

Request (excuting)

// @param string $request SQL query
// @param array|null $values Optional values
// @return bool
$values = $DB->execute($request, $values = array());


// Exemple 1       
$request = $DB->execute("DELETE FROM users"); // Delete all users
