Status of PHP PDO_Firebird as of December 2011
If you have read the previous article about Firebird pdo status then you might now that almost all worked except binding parameters by name (see bug #48877).
But as a gift bug #48877 is fixed in svn , and is already in the php snapshots for 5.4.x,5.3.x and trunk 5.5.x
So it should all work from the mentioned article , There are still some bugs left but it will be fixed until the end of the year : Bugs #47415 and #53280 are already done from my todo list
