Apache 2.2.X configuration
Add the next line to the Apache 2.2.x httpd.conf configuration:
LoadFile "C:/Program Files/PostgreSQL/{version}/bin/libpq.dll"Above line must be entered before the next line.
LoadModule php5_module "c:/wamp/bin/php/php5.2.11/php5apache2_2.dll"
PHP 5.2.X Configuration
Enable the following two lines in the php.ini configuration file. By 'Enable' i mean, remove trailing ; (semicolon). By these, you un-comment the line.
extension=php_pdo_pgsql.dllextension=php_pgsql.dllRestart WAMP
Test by adding this in your index.php
echo extension_loaded('pgsql') ? 'yes':'no';(source: http://www.plaatsoft.nl/wamp-postgresql-integration/)
if we install WAMP server, we will get two php.ini files. one in C:\wamp\bin\php\php5.3.5 and another in C:\wamp\bin\apache\Apache2.2.17\bin.
if we execute a php file from browser, then php.ini file in C:\wamp\bin\apache\Apache2.2.17\bin will be referred.if we execute a php file from command line, then php.ini file in C:\wamp\bin\php\php5.3.5 will be referred.
what ever the changes i made enable/disable the dll in PHP->PHP extensions,all the changes will be saved in C:\wamp\bin\apache\Apache2.2.17\bin\php.ini file. but C:\wamp\bin\php\php5.3.5\php.ini file remains unchanged.
for my problem, i made the following changes
uncommented, extension=php_pdo_pgsql.dll,uncommented, extension=php_pgsql.dll,uncommented, extension_dir = "c:/wamp/bin/php/php5.3.5/ext/",in C:\wamp\bin\php\php5.3.5\php.ini file. Now its working good. :)
