Question

我们过去只包含存储在{project_root}/includes文件夹中的类。我们使用自动加载功能在我们的应用程序中包含我们需要的类。现在我想使用一些库，我遇到了一个问题：

1）自动加载：

// {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）我想使用的代码：

//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）错误：

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

我尝试使用类似这样的内容：autoloading classes in subfolders，但仍然可以使用 Class 'Monolog\Logger' not found

请尝试使用此自动加载功能：

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

它将\替换为/以匹配路径
从includes/目录进行搜索。

您也可以考虑在includes/ php指令中添加include_path路径：

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

PHP无法自动加载类
