As Nikita said, that has been fixed, but it seems noteworthy that
no PDOException is thrown in this case, but rather TypeError, see
<https://3v4l.org/jfChu>.

This has been fixed in PHP 7.0 as part of https://wiki.php.net/rfc/internal_constructor_behaviour.

Description:
------------
PDO contructer return null and output warning() when given unexpected type arguments.
I think it is better that throw PDO exception with relevant message or update PHPDoc to indicate
this specification.
How about that?
Test script:
---------------
<?php
try {
$pdo = new PDO('pgsql:host=db;dbname=hoge', 'postgres', [], []);
var_dump(is_null($pdo));
} catch(PDOException $e) {
var_dump($e->getMessage());
}
Expected result:
----------------
string(64) "PDO::__construct() expects parameter 3 to be string, array given"
Actual result:
--------------
Warning: PDO::__construct() expects parameter 3 to be string, array given in
/Users/kazushige.tominaga/test-prestissimo/hoge.php on line 2
bool(true)
