cviebrock / find_class_strings.php
Last active September 13, 2024 00:21
PHP function that uses AST to try and find all instances of strings that are class names (so you can convert them to `MyClass::class`)
<?php declare(strict_types=1);
/**
* PHP script that uses composer files to find all classes in a project,
* then uses AST to try and find all instances of string expressions in the project,
* then filters that list of string expressions to those that match class names.
*
* The idea is to look for instances of:
*
* someFunction('MyClass');

Replacement for Laravel 3.2's crypter class, that doesn't require mcrypt
<?php namespace Laravel; defined('DS') or die('No direct script access.');
/**
* The mcrypt library was deprecated in PHP7.2, so I couldn't run old Laravel 3.2
* applications anymore. Rather than upgrade the whole application, you can just
* replace the `/laravel/crypter.php` file with this one, which uses the
* OpenSSL library instead of mcrypt.
