Bug description: What is the default type of bindParam(), bindValue() and
execute(array) ? (PDO)
Description:
------------
I was wondering what is the default type of parameter when none is set?
Reproduce code:
---------------
If I run that code :
$dbh = new PDO(
'mysql:host=localhost;dbname=xxx', 'xxx', 'xxx');
$stmt = $dbh->prepare('SELECT ? FROM DUAL WHERE 1 = ?');
var_dump($stmt->execute(array('aa\'aa', 'aaa')));
This dump true, meaning that 'aaa' was casted to a string and that the
actual query looks like this in mySQL :
SELECT 'aa''aa' FROM DUAL WHERE 1 = 'aaa'
Expected result:
----------------
The documentation should indicate that when no type is provided (while
calling bindParam(), bindValue(), or execute()), PDO::PARAM_STRING is
used.
Actual result:
--------------
Neither bindParam(), bindValue() or execute() speak of a default type, nor
the main page of PDO (http://fr.php.net/manual/en/ref.pdo.php) describe it.
Thus, we could expect anything from the driver (like casting variable into
integer instead of string).
