The PHP development team joined the PDO module from v5.1, and he defined a lightweight, consistent interface for the PHP Access database, which provides a data access abstraction layer so that whether you're using MySQL, MSSQL, or any other database, You can perform SQL operations with the same function. Note that you cannot use the PDO extension itself to perform any database operations, and you must access the database server using a database-specific PDO driver (PDO-driven for a particular database).
Program development has a common subconscious character: the docking and upgrade of the program is better, that is, with the continuous development of PHP, PHP is destined to promote its PDO rather than provide more support for the ADODB interface, so that the program development needs to be updated in our minds, quickly accept new things , as has been criticized IE6, although the current user population is very large, but, Microsoft's newly released operating system will not be IE6, and will not provide too much support for IE6.
I belong to the top PDO one of the users, unified interface why not to use, but to the conservative, I think the major open source program should actively use the new PHP technology, to develop new technology, to help PHP continue to develop, some time ago there is a manuscript called "IE6 Not Dead, the internet is not developed", may be a bit drastic , but today I want to say, PDO not live, PHP can not be developed.
Biweb Station program in this do I am more appreciative, under pressure, they are still in PDO support up and down the hard kungfu, this will inevitably lead to their future expansion space will be very large, Support PHP5.3 Even the future PHP6 will be completely no problem, I hope that other source code can also quickly join this function, in the PHP industry set off a PDO heat.
