PHP cannot open Pgsql extension solution under Windows

TIP: Environment windows8.1 64-bit + xampp1.8.1 + PostgreSQL 9.3.6-2

The first step:

php.ini Open Pgsql Extension extension=php_pgsql.dll (if PDO connection is on Extension=php_pdo_pgsql.dll)

Step Two:

Configuring the Bin directory of the Pgsql to environment variables

Step Three:

Copy the DLL files from the Pgsql installed Bin directory to the system SysWOW64 directory

Copy files are:

Libeay32.dll
Libiconv.dll
Libintl.dll
Libpq.dll
Ssleay32.dll

Part fourth:

Restart Apache, see the phpinfo pgsql extension, that is, the successful opening of the pgsql extension

Tip: The above is not in order, the first three items can be completed after configuration!
