Php spl_自动加载时出现致命错误

我这里有一段自动加载类的代码：

<?php
$test = [
            'includeDirs' => [
                'interfacesDir' => __DIR__ . DIRECTORY_SEPARATOR . 'interfaces'. DIRECTORY_SEPARATOR,
                'abstractsDir' => __DIR__ . DIRECTORY_SEPARATOR . 'abstracts'. DIRECTORY_SEPARATOR,
                'classesDir' => __DIR__ . DIRECTORY_SEPARATOR . 'classes'. DIRECTORY_SEPARATOR
            ],
            'includeExtensions' => [
                'classExtension' => '.class.php',
                'abstractExtension' => '.abstract.php',
                'interfaceExtension' => '.interface.php'
            ]
        ];

set_include_path('.');
set_include_path(get_include_path() . PATH_SEPARATOR . implode(PATH_SEPARATOR, $test['includeDirs']));

spl_autoload_extensions(implode(',', $test['includeExtensions']));
spl_autoload_register();

$streamFactory = new StreamFactory();

---

您需要将
StreamFactory
类的名称更改为
stream\u factory
，并使用
$StreamFactory=new stream\u factory（）实例化它
或将文件'stream_factory.class.php'重命名为
StreamFactory.class.php

index.php

<?php

error_reporting(-1);
ini_set('display_errors', 'On');

$test = [
  'includeDirs' => [
    'interfacesDir' => __DIR__ . DIRECTORY_SEPARATOR . 'interfaces'. DIRECTORY_SEPARATOR,
    'abstractsDir' => __DIR__ . DIRECTORY_SEPARATOR . 'abstracts'. DIRECTORY_SEPARATOR,
    'classesDir' => __DIR__ . DIRECTORY_SEPARATOR . 'classes'. DIRECTORY_SEPARATOR
  ],
  'includeExtensions' => [
    'classExtension' => '.class.php',
    'abstractExtension' => '.abstract.php',
    'interfaceExtension' => '.interface.php'
  ]
];

set_include_path('.');
set_include_path(get_include_path() . PATH_SEPARATOR . implode(PATH_SEPARATOR, $test['includeDirs']));

spl_autoload_extensions(implode(',', $test['includeExtensions']));
spl_autoload_register();

try {
  $streamFactory = new \stream_factory();
} catch(Exception $e) {
  echo $e->getMessage();
}

<?php
class stream_factory {
  function __construct() {
    echo "Hello from " . __CLASS__;
  }
}

StreamFactory类的位置在哪里？它是
classes
？是的，它在这里：C:\Users\Test\PhpstormProjects\Test\classes\stream\u factory.class.php还有一个问题，StreamFactory使用的名称空间是什么？我没有设置任何名称空间。它是全局的。您是否尝试过
$streamFactory=new\streamFactory（）？
