WrongCaseClass

A class, interface, or enum is referenced with casing that differs from its declaration. PHP class name resolution is case-insensitive at runtime, but consistent casing is expected by autoloaders and static analysis tools.

Example

<?php
class HttpClient {}

$client = new httpclient(); // wrong casing: should be HttpClient

How to fix

Update the reference to use the exact casing from the class/interface/enum declaration.
