我试着获取控制器文件列表
$files = scandir(APP_DIR . '/Controller/');
...但是我收到了这个错误:
Warning (2): scandir(src/Controller/): failed to open dir: No such file or directory [APP/Controller/HomeController.php, line 13]
...当我尝试从列表中删除一些文件名时:
$files = array_diff( $files, array('.','..','Component','AppController.php','HomeController.php'))
;
...我收到此错误:
Warning (2): array_diff() [function.array-diff]: Argument #1 is not an array [APP/Controller/HomeController.php, line 23]
我的全班同学看来:
<?php
namespace App\Controller;
use ReflectionClass;
use ReflectionMethod;
class HomeController extends AppController{
public function index(){
/**

$files = scandir(APP_DIR . '/Controller/');
$controllers = [];
$ignoreFilesList = [
'.',
'..',
'Component',

$files = array_diff( $files, array('.','..','Component','AppController.php','HomeController.php'));
$className = '';
$class = null;
$ignoreList2 = ['beforeFilter', 'afterFilter', 'initialize', 'delete'];
echo is_array ( (array)$files );// returns 0 without cast
foreach( (array)$files as $file){
$controller = str_replace('Controller', '', explode('.', $file)[0]);
array_push($controllers, $controller); //str_replace('Controller', '', $controller));
//dump( $controller );
/* controller methods */
$this->$className = 'App\\Controller\\'.$controller.'Controller';
$this->$class = new ReflectionClass($this->$className);
$methods = $this->$class->getMethods(ReflectionMethod::IS_PUBLIC);

foreach($methods as $method){

虽然PHP文档没有说明任何内容,但 scandir 通常对相对路径不起作用。 (虽然有些情况下相对路径可以很好地工作。)
由于APP_DIR
存储单个目录名而不是路径,因此scandir将尝试访问src/Controller/
,这可能与当前正在运行的脚本无关。
$files = scandir(APP_DIR . '/Controller/');
APP
构建完整路径感谢ndm在他对OP的评论中提醒我们APP
常数。 APP
存储应用程序目录的绝对路径,包括尾部斜杠。
$path = APP .'Controller/';
$files = scandir($path);
$path = $_SERVER['DOCUMENT_ROOT'] . '/'. APP_DIR .'/Controller/';
$files = scandir($path);
或者, 可以 能够使用PHP: Realpath来检索完整路径。 *提醒:工作目录会因运行的脚本而异。
