当在 PHP 中使用 ::class 但在 Visual Studio Code 中未使用 class 时收到警告的扩展

Question

Is there any PHP extension for Visual Studio Code that can warn you in case you are doing::class in PHP but the class is not use d on top of the file?

Let me show you a simple dummy example that proves my point:

<?php

declare(strict_types=1);

namespace Src\Users;

class ExampleClass
{
    protected string $anotherClass = AnotherExampleClass::class;
}

If you copy and paste this code on a PHP project in VSCode it won't highlight in red the $anotherClass declaration, even though AnotherExampleClass is not use d after the namespace line and is a class that is not within the same folder as ExampleClass .

This won't even work for me with PHP Intelephense and PHP IntelliSense extensions enabled.

Thanks in advance.

Answer 1

if you want the class to be added automatically you can use spl_auto_register. Because sometimes it can be difficult to track the location of the files. for ex.

spl_autoload_register(function ($class) {
global $dir;
if (file_exists($dir. $class . ".php")) {
    include $dir. $class . ".php";
} elseif (file_exists($class . ".php")) {
    include  $class . ".php";
}

});

You can check again with  is_file or file_exists .

No syntax errors in this file. Namespace not mapped to single directory ie need analyze all project and vendor classes(try all registered auto-loaders).
