PHP無法自動載入類

Question

我們以前只包含存儲在{project_root}/includes文件夾中的類。我們使用自動加載功能在我們的應用程序中包含我們需要的類。現在，我想用一些圖書館，我面臨着一個問題：

1）自動加載：

// {project_root}/includes/autoLoad.php 
// There is a global_connfig.php file that loads by directive in php.ini 
// auto_prepend_file = /var/www/global_config.php which includes autoload.php file and sets the include path to {project_root}/includes 
function __autoload($classname){ 
    include "$classname.php"; 
} 

2）的代碼，我想用：

//just an example from the monolog reference 
// I put Monolog folder with it's subfolders in {project_root}/includes 
use Monolog\Logger; 
use Monolog\Handler\StreamHandler; 

$log = new Logger("name"); 
$log->pushHandler(new StreamHandler(LOGSPATH . '/monolog', Logger::WARNING)); 


$log->warning('Foo'); 
$log->error('Bar'); 

3）錯誤：

Warning: include(Monolog\Logger.php): failed to open stream: No such file or 
directory in {project_root}/includes/autoLoad.php 

我試着用這樣的東西：autoloading classes in subfolders，但仍然得到 Class 'Monolog\Logger' not found

問題更新

Answer 1

試試這個自動加載函數：

function __autoload($classname) 
{          
    $filename = str_replace("\\", "/", $classname).".php";  
    include __DIR__."/$filename";          
} 

• 它取代\與/匹配路徑
• 它從includes/目錄搜索。

你也可以考慮加入includes/路徑您include_path PHP指令：

set_include_path(get_include_path() . PATH_SEPARATOR . "{project_root}/includes");
