<?php

try {
   $dbh = new PDO('pgsql:host=localhost;port=5432;dbname=###;user=###;password=##');
   echo "PDO connection object created";
}
catch(PDOException $e)
{
      echo $e->getMessage();
}

?>

我收到错误消息"无法加载驱动程序"

我很难用pgsql设置laravel 5.3（在wamp / windows上运行）。当我尝试使用“ php artisan migration”迁移表时，出现错误“ PDO异常-无法找到驱动程序”

1. 我安装了postgres 9.6。
2. 我为postgresql启用了php扩展名：

3.我将postgres库添加到环境路径变量

4. 我用php测试了pdo postgres连接，并且可以连接了：

    $dbh = new PDO("pgsql:dbname=rotocms;host=127.0.0.1", "postgres", "mypassword");

    if($dbh){
     echo "connected";
    }else{
     echo 'there has been an error connecting';
    }

所以我被困住了，无法在Laravel中进行迁移。我的.env：

    DB_CONNECTION = pgsql
    DB_HOST = 127.0.0.1
    DB_PORT = 5432
    DB_DATABASE =我的数据库名称
    DB_USERNAME = postgres
    DB_PASSWORD =密码

这是laravel错误堆栈：
