php用のpgsqlモジュールをインストールする必要があります。debian /ubuntuでは次のようなものです：

sudo apt-get install php5-pgsql

または、パッケージがインストールされている場合は、php.iniでdemoduleを有効にする必要があります

extension=php_pgsql.dll (windows)
extension=php_pgsql.so (linux)

Greatings。

Try this:

Uncomment the following in php.ini by removing the ";"

;extension=php_pgsql.dll

Use the following code to connect to a postgresql database server:

pg_connect("host=localhost dbname=dbname user=username password=password")
    or die("Can't connect to database".pg_last_error());

Enable PHP to work with PostgreSQL in Apache

In Apache I edit the following configuration file: C:\xampp\php.ini

I make sure to have the following lines uncommented:

extension=php_pgsql.dll 
extension=php_pdo_pgsql.dll

Finally restart Apache before attempting a new connection to the database engine.

Also, I leave my code that ensures that the connection is unique:

private static $pdo = null;

public static function provideDataBaseInstance() {
    if (self::$pdo == null) {
        $dsn = "pgsql:host=" . HOST .
               ";port=5432;dbname=" . DATABASE .
               ";user=" . POSTGRESQL_USER .
               ";password=" . POSTGRESQL_PASSWORD;
        try {
            self::$pdo = new PDO($dsn);
        } catch (PDOException $exception) {
            $msg = $exception->getMessage();
            echo $msg . 
                 ". Do not forget to enable in the web server the database 
                  manager for php and in the database instance authorize the 
                  ip of the server instance if they not in the same 
                  instance.";
        }
    }
    return self::$pdo;
}

I installed PHP on windows IIS using Windows Platform Installer (WPΙ). WPΙ creates a "PHP Manager" tool in "Internet Information Services (IIS) Manager" console. I am configuring PHP using this tool.

in http://php.net/manual/en/pdo.installation.php says:

PDO and all the major drivers ship with PHP as shared extensions, and simply need to be activated by editing the php.ini file: extension=php_pdo.dll

so i activated the extension using PHP Manager and now PDO works fine

PHP manager simple added the following two lines in my php.ini, you can add the lines by hand. Of course you must restart the web server.

[PHP_PDO_PGSQL]
extension=php_pdo_pgsql.dll

I and many other shave spent way too long on this - this needs a massive improvement. After spending hours, I finally copied php_pgsql.dll from php's ext directory to Apache24's root directory (wherever you installed it) and finally Apache was able to get the php/pg modules and dlls loaded.

$dbh = new PDO('pgsql:host=localhost;port=5432;dbname=###;user=###;password=##');

For PDO type connection uncomment

extension=php_pdo_pgsql.dll and comment with

;extension=php_pgsql.dll

$dbh = pg_connect("host=localhost dbname=### user=### password=####");

For pgconnect type connection comment

;extension=php_pdo_pgsql.dll and uncomment

extension=php_pgsql.dll

Both the connections should work.
