所以我正在学习PHP，并从一些非常基础的东西开始。
我正在尝试从我的控制器文件夹中的文件调用一个函数，但它不起作用。
我已成功地将我输入的任何内容回显到URL栏中，但它不会在我的其他index.php文件中打印出作为控制器一部分的消息，但当然会继续回显任何消息输入的URL。我错过了什么吗？
所以这就是我坐在我的MVC文件夹之外的一个index.php文件：
<?php
$url = $_GET['url'];
echo $url;
require 'controllers/' . $url . '.php';
$controller = new $url;
?>
以下是我在我想要调用的controllers文件夹中的index.php文件中的内容：
<?php
class Index {
function __construct(){
echo 'We are in index';
}
}
?>
我的.htaccess文件如下所示：
RewriteEngine On
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l
RewriteRule ^(.*)$ /index.php?url=$1 [QSA,L]

如果您使用的是Linux，请将execute()更改为@interface LinksTableViewController (){
NSArray *data;
}
@property (strong, nonatomic) NSArray *links;
@property (strong, nonatomic) NSArray *tNames;
@property (strong, nonatomic) NSArray *dThor;
@property (strong, nonatomic) NSArray *theLinker;
@property (strong, nonatomic) NSArray *anText;
@property (strong, nonatomic) NSArray *noDo;
@end
@implementation LinksTableViewController

}
，然后尝试使用小写字母访问索引。
