Note: Debian system's PHP (as the current mainstream development language) external modules require two files to be activated, one is the pdo.so we just compiled
and another pdo is required. If you don’t know how to write the info file
, just fry the following:
package="pdo"
extname="PDO"
dsoname="pdo"
sapilist="apache(Unix platform The most popular WEB server platform) apache (The most popular WEB server platform on Unix platform) 2 cgi (not many people are using it now) cli fcgi (Not many people are using it now)"
depends=""
priority="500"
architecture="any"
Then run:
#》 /usr /sbin/php(as the current mainstream development language)5-modconf apache(the most popular WEB server platform on Unix platform)2
The system will prompt you which modules you need , select pdo and confirm
pdo is installed successfully
Now install pdo_pgsql-0.9

#》pear download pdo_pgsql-0.9
#> tar zxf PDO_PGSQL-0.9 .tgz
#>cd PDO_PGSQL-0.9
#>php(as the current mainstream development language)ize
#>./configure
#>make
#>make install
Then repeat the above process of installing pdo: modify pdo_pgsql.info
package="pdo_pgsql"
extname="PDO_PGSQL"
dsoname="pdo_pgsql"
sapilist="apache (The most popular WEB server platform on Unix platform) apache(The most popular WEB server platform on Unix platform)2 cgi(Not many people are using it now) cli fcgi(Not many people are using it now)"
depends=""
priority="500"

Run
#》/usr/sbin/php(as the current mainstream development language)5-modconf apache(the most popular WEB server platform on Unix platform)2
Select the pdo_pgsql module
ok everything is ready
#》apache(the most popular WEB server platform on Unix platform)2 -k restart
Edit test module:

// Connect to an ODBC database using driver invocation

$host=xxxx.xxxx.com;
$port=5433;
$dbname=test;
$user=xxxxxx;
$password=xxxxxxxxx;
//$ 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]." ";
print $row[cpdh] . " ";
