如何更改 PHP 脚本以使用 PDO？

Question

旧查询用于获取管理员存储在数据库中的网站设置，例如 MyCompanyName 或 Copyright 文本。这些是由管理员添加到网站后端的。

<?php 

error_reporting (E_ALL ^ E_NOTICE);

include("connection.php");

include('english.php');

include("admin/include/function.php");

$query_general_setting=mysql_fetch_array(mysql_query("select * from general_setting where id=1 and g_id=1"));

if(basename(url())!="index.php" or basename(url())!="index.php?log=1"){

$explode_permistion=explode(",",$_SESSION['area_permistion']);

}



?>

        <title><?php echo $query_store_setting['s_title'];?></title>

        <meta name="description" content="<?php echo $query_store_setting['s_description'];?>">

        <meta name="keywords" content="<?php echo $query_store_setting['s_keywords'];?>">

        <link rel="stylesheet" href="style.css"> 

</head>

改成这个没什么用：

$query_store_setting = $conn->query('SELECT * FROM general_setting WHERE id=1 and g_id=1')->fetchAll();

Answer 1

如果只有一行

$query_store_setting = $conn->query('SELECT * FROM general_setting WHERE id=1 and g_id=1')->fetch();

不止一个

$result = $conn->query('SELECT * FROM general_setting WHERE id=1 and g_id=1')->fetchAll();
 foreach($result as &$row) {
      $query_store_setting = $row;
      //do sth..
 }
