CodeIgniter extensions and rules for PHPStan

• PHPStan
• CodeIgniter

This extension provides the following features:

• Type inference

Rules

• Checks if the string argument passed to config() or model() function is a valid class string extending CodeIgniter\Config\BaseConfig or CodeIgniter\Model, respectively. This can be turned off by setting codeigniter.checkArgumentTypeOfFactories: false in your phpstan.neon. For fine-grained control, you can individually choose which factory function to disable using codeigniter.checkArgumentTypeOfConfig and codeigniter.checkArgumentTypeOfModel. NOTE: Setting codeigniter.checkArgumentTypeOfFactories: false will effectively bypass the two specific options.
• Checks if the string argument passed to service() or single_service() function is a valid service name. This can be turned off by setting codeigniter.checkArgumentTypeOfServices: false in your phpstan.neon.
• Disallows instantiating cache handlers using new and suggests to use the CacheFactory class instead.
• Disallows instantiating FrameworkException classes using new.
• Disallows direct re-assignment or access of $_SERVER and $_GET and suggests to use the Superglobals class instead.
• Disallows use of ::class fetch on config() and model() and suggests to use the short form of the class instead.
