pdo作為下一個php的數(shù)據(jù)庫統(tǒng)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(jīng)過測試，pdo聯(lián)結比adodb快3倍左右，和直接聯(lián)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(shù)據(jù)庫：postgres8.0.3硬件：C4-1.7g;384M安裝pdo需要php的開發(fā)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?。。?！#>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(shù)據(jù)庫中的數(shù)據(jù)了祝賀你?。?！
