How can the use of uppercase letters in class names affect autoloading in PHP?

Using uppercase letters in class names can cause issues with autoloading in PHP because PHP is case-sensitive when it comes to class names. To avoid problems with autoloading, it is recommended to follow the PSR-4 standard for class naming conventions, which suggests using StudlyCaps (also known as PascalCase) for class names. 

// Autoloading using PSR-4 standard with Composer
// File structure: 
// - /src
//   - MyClass.php

// Composer autoloader
require 'vendor/autoload.php';

// Define namespace and class name following PSR-4 standard
namespace MyNamespace;

class MyClass {
    // Class implementation
}
