今天我想写一个简单的php脚本，但我遇到了一些烦人的错误。我只是简单地包含 config.php 文件并尝试访问 root_path 变量但没有成功。还有 2 个其他警告仅在我包含 config.php 文件时才显示。
这些文件在最新的 xampp 上运行。
smarty_setup.php ：
<?php
require('config.php');
require($root_path . '/libs/Smarty.class.php');
class FileHosting extends Smarty {
function __construct()
{
parent::__construct();
$this->setTemplateDir($root_path . '/templates/');
$this->setCompileDir($root_path . '/templates_c/');
$this->setConfigDir($root_path . '/configs/');
$this->setCacheDir($root_path . '/cache/');
$this->caching = Smarty::CACHING_LIFETIME_CURRENT;
$this->assign('app_name', 'File Hosting');
}
}
?>
配置.php ：
<?php
$root_path = 'D:/xampp/htdocs/example';
$db_user = 'xxx';
$db_password = 'xxx';
$db_name = 'xxx';
$db_host = 'xxx';
$facebook_appID = 'xxx';
$facebook_secret = 'xxx';
?>
错误：

谢谢你帮助我。
在您的类中，您正在访问全局范围内的 $root_path。将其传递给构造函数：
class FileHosting extends Smarty {
// Pass $root_path as a param to the constructor
function __construct($root_path)
{
parent::__construct();
$this->setTemplateDir($root_path . '/templates/');
$this->setCompileDir($root_path . '/templates_c/');
$this->setConfigDir($root_path . '/configs/');
$this->setCacheDir($root_path . '/cache/');
$this->caching = Smarty::CACHING_LIFETIME_CURRENT;
$this->assign('app_name', 'File Hosting');
}
}
// Instantiate as
$smarty = new FileHosting($root_path);
这些错误中的第一个令人费解，因为它表明config.php没有正确包含。
Notice: Undefined variable: root_path in D:'xampp'htdocs'example'includes'smarty_setup.php on line 3
如果这些确实是config.php的唯一内容（例如，您没有在函数中设置这些变量），则不应首先收到root_path通知。
更新
如果无法在相对路径中包含config.php，请确保：
-
config.php与您尝试从中包含它的文件位于同一目录中 - 检查您的 PHP
include_path，确保它包含当前目录.：
.
echo get_include_path();
尝试将 $root_path 设置为常量而不是变量：
define('ROOT_PATH', 'D:/xampp/htdocs/example');
然后像这样使用它：
$this->setTemplateDir(ROOT_PATH . '/templates/');
