在项目中重构 require_once 文件 [英] Refactoring require_once file in a project
问题描述
我是 PHP 初学者.我正在使用此目录层次结构进行项目:model
、control
、view
和 helper
文件夹位于我的项目文件夹
I'm a beginner in PHP. And i'm working on project with this directories hierarchy : model
, control
, view
and helper
folders are in my project folder
现在我正在尝试在 control
和 model中的每一个中编写一个文件
init.php
和 require_once
code> 文件,这是我的 init.php
Now i'm trying to write a file init.php
and require_once
it in each of control
and model
files, here's my init.php
<?php
$current_dir = basename(getcwd());
$model_dir = "model";
$helper_dir = "helper";
function require_helper(){
$handle = opendir("../{$helper_dir}");
while($file = readdir($handle)){
if($file != "." && $file != ".."){
require_once "../{$helper_dir}/{$file}";
}
}
}
if($current_dir == "control"){
$handle = opendir("../{$model_dir}");
while($file = readdir($handle)){
if($file != "." && $file != ".."){
require_once "../{$model_dir}/{$file}";
}
}
require_helper();
} elseif( $current_dir == "model") {
$handle = opendir($current_dir);
while($file = readdir($handle)){
if($file != "." && $file != ".."){
require_once "{$file}";
}
}
require_helper();
}
?>
但是当我测试我的项目时出现此错误:
But when i test my project i get this error :
注意:未定义变量:session in C:\wamp\www\harmony\control\login.php 第 11 行
Notice: Undefined variable: session in C:\wamp\www\harmony\control\login.php on line 11
这是我的 login.php
文件:
<?php
require_once "../helper/init.php";
?>
<?php
if(isset($_GET["logout"]) && $_GET["logout"] == "true" ){
$session->logout();
}
if($session->is_logged_in()){
redirect_to("../view/index.php");
}
if(isset($_POST["submit"])){
$username = $db->escape_value($_POST["username"]);
$password = $db->escape_value($_POST["password"]);
$password = hash('sha1' , $password);
$arr = User::auth($username , $password);
if($arr){
$usr = $db->instantiate($arr);
$session->login($usr);
} else {
Session::notify("Invalid login information.");
}
}
?>
你能帮我吗?怎么了?
推荐答案
您正在尝试访问函数内部的 $current_dir、$model_dir 和 $helper_dir.您不能访问在函数外部声明的变量,除非它们被声明为全局变量,否则实际上传递给函数.
You're trying to access $current_dir, $model_dir and $helper_dir inside of functions. You can't access variables which were declared outside of a function unless they are declared global, or else actually passed into the function.
例如:
function require_helper(){
global $helper_dir;//this is key
$handle = opendir("../{$helper_dir}");
while($file = readdir($handle)){
if($file != "." && $file != ".."){
require_once "../{$helper_dir}/{$file}";
}
}
}
