PHP Data Objects Interface.
Do not use this, as PDO has been moved into core (the php source) so this pecl extension is dead.
PDO provides a uniform data access interface, sporting advanced features such
as prepared statements and bound parameters. PDO drivers are dynamically
loadable and may be developed independently from the core, but still accessed
using the same API.
This package is not maintained anymore and has been superseded. Package has moved to channel http://svn.php.net/viewvc/php/php-src/trunk/ext/pdo/ package ext/PDO.
It is highly recommended that you update to PHP 5.1 or higher before using PDO.
This PECL release corresponds to the PHP 5.1.3 release.
You need to install a PDO database driver to make use of PDO,
for a list of available PDO drivers.
If you are running on Windows, you can find a precompiled binary at:
