php - Why can't I connect to my psql db? -

so trying link page a.php psql db.

here's dbconnection.class.php:

<?php  class dbconnection {     var $conn      function dbconnection();     {     $this->conn = pg_connect("host='localhost' port='5432' dbname='tester' user='postgres' password='password'") or die("unable connect");     } } ?> 

and here's a.php

<?php include ("dbconnection.class.php"); $dbconnection = new dbconnection(); ?> 

it keeps telling me have error on line 7 of dbconnection: fatal error: non-abstract method dbconnection::dbconnection() must contain body in c:\wamp\www\dbconnection.class.php on line 7

i'm not entirely sure far fixing problem

open php.ini  find ;extension=php_pgsql.dll , remove initial semi colon find ;extension=php_pdo_pgsql.dll , remove initial semi colon  save file restart apache 

remove

;

from end of function name

class dbconnection {     var $conn      function dbconnection()     {     $this->conn = pg_connect("host='localhost' port='5432' dbname='tester' user='postgres' password='password'") or die("unable connect");     } } ?>
