pdo作為下一個php的數據庫統一接口，目前的版本是0.9，看來不久就可以release了，搶先嘗鮮。經過測試，pdo聯結比adodb快3倍左右，和直接聯結相差很小。測試工具：AB測試條件Apache/2.0.54 (Debian GNU/Linux) mod_fastcgi/2.4.2 PHP/5.0.4-0.10 mod_perl/2.0.1 Perl/v5.8.7 Server at 127.0.0.1 Port 80數據庫：postgres8.0.3硬件：C4-1.7g;384M安裝pdo需要php的開發工具包以及gccg++,當然也需要php的php5-dev安裝PDO_pgsql需要libpg-dev以上軟件一定要apt-get否則會失敗！！！#>pear remote-info pdopear remote-info pdo

好了，在你的瀏覽器上輸入http://localhost/pdotest.php你是否看到你數據庫中的數據了祝賀你！！！
