pdo作為下一個(gè)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(cè)試，pdo聯(lián)結(jié)比adodb快3倍左右，和直接聯(lián)結(jié)相差很小。測(cè)試工具：AB測(cè)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(dāng)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(huì)失敗！！！#>pear remote-info pdopear remote-info pdo
