安装pdo需要php的开发工具包以及gcc\g++,当然也需要php的php5-dev
安装PDO_pgsql需要libpg-dev以上软件一定要apt-get否则会失败！！！
#>pear remote-info pdo

哈，还是不知道版本好，到http://pecl.php.net/搜搜，目前版本0.9
OK
#》pear install pdo-0.9
pear会帮你安装好的
编译好的模块放在了：/usr/lib/php5/20041030/ 目录下
#>cd /usr/lib/php5/20041030/
注意：debian系统的php外部模块需要两个文件才能被起动，一个是我们刚编译的pdo.so
另外还需要一个pdo.info文件
不会写就炒下面的：
package="pdo"
extname="PDO"
dsoname="pdo"
sapilist="apache apache2 cgi cli fcgi"
depends=""
priority="500"
architecture="any"
然后运行：
#》 /usr/sbin/php5-modconf apache2
系统会提示你需要哪些模块，选中pdo确定
pdo就安装成功了
下面安装pdo_pgsql-0.9
这个需要按下面步骤进行：
#》pear download pdo_pgsql-0.9
#> tar zxf PDO_PGSQL-0.9.tgz
#>cd PDO_PGSQL-0.9
#>phpize
#>./configure
#>make
#>make install
然后重复上面安装pdo的过程：修改pdo_pgsql.info
package="pdo_pgsql"
extname="PDO_PGSQL"
dsoname="pdo_pgsql"
sapilist="apache apache2 cgi cli fcgi"
depends=""
priority="500"
architecture="any"
运行
#》 /usr/sbin/php5-modconf apache2
选择pdo_pgsql模块
ok 一切就绪
#》apache2 -k restart
编辑测试模块：

// Connect to an ODBC database using driver invocation

$host='xxxx.xxxx.com';
$port='5433';
$dbname='test';
$user='xxxxxx';
$password='xxxxxxxx';
//$cc = "host=$host,dbname=$dbname,port=$port";
$dsn = "pgsql:host=$host port=$port dbname=$dbname user=$user password=$password";


try {
$dbh = new PDO($dsn, $user, $password);
} catch (PDOException $e) {
echo 'Connection failed: ' . $e->getMessage();
}

$sql='select * from cpjcsj';
foreach ($dbh->query($sql) as $row) {
print $row['cpdm']."\t";
print $row['cpdh'] . "\t";
print $row['cpmc'] . "\n";
}

?>



好了，在你的浏览器上输入http://localhost/pdotest.php
你是否看到你数据库中的数据了
祝贺你！！！
