PDO is seriously crap. Having used .NET's beautiful ADO.Net, PDO almost feels like
something thrown together by a college student. It's no wonder the community is
dropping PHP like a brick if this is the sort of developments being made these
days.

No bug here. This is how crappy PDO works ever since. If you don't specify a bind type, binding
will use strings. Your code:
$stmt = $db->prepare("INSERT INTO mytable (mybit) VALUES (?)");
$stmt->execute(array(0));
... is equivalent to:
$stmt = $db->prepare("INSERT INTO mytable (mybit) VALUES ('0')");
$stmt->execute(array(0));
Which in turn inserts 1 into the BIT column.

Description:
------------
When trying to insert a row with a 0-value into a column of type BIT(1), if the value for the column
is not hard-coded into SQL statement, it causes the value to be inserted to become 1. If it is
hardcoded, it is okay.
Reproduce code:
---------------
/* This results in the value of the column being set to 1 (incorrect) */
$db = new PDO ( "mysql:dbname=db1234;host=localhost", "user1234",
"pass1234" );
$stmt = $db->prepare("INSERT INTO mytable (mybit) VALUES (?)");
$stmt->execute(array(0));
db_disconnect($db);
/* This results in the value of the column being set to 0 (correct) */
$db = new PDO ( "mysql:dbname=db1234;host=localhost", "user1234",
"pass1234" );
$stmt = $db->prepare("INSERT INTO mytable (mybit) VALUES (0)");
$stmt->execute();
db_disconnect($db);
Actual result:
--------------
The first example inserts a row with the column value set to 1 (wrong)
The second example inserts a row with the column value set to 0 (right)
