Question

所以我试图将我的页面a.php链接到我的psql db。

这里是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 to connect");
    }
}
?>

和这里的a.php

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

它一直告诉我在DBConnection的第七行有一个错误：致命错误：非抽象方法DBConnection :: DBConnection（）必须在第7行的C：\ wamp \ www \ DBConnection.class.php中包含body < / p>

我不完全确定我在解决这个问题方面做了什么

Answer 1

Open php.ini 
Find ;extension=php_pgsql.dll and remove the initial semi colon
Find ;extension=php_pdo_pgsql.dll and remove the initial semi colon 
Save the file
Restart apache

删除

从函数名称的末尾开始

class DBConnection
{
    var $conn

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

为什么我无法连接到我的psql数据库？
