Fix PHPStan errors in the file(s) or directory specified in $ARGUMENTS.

When making changes to a function

• Add types to parameters where you can infer them confidently from call sites
• Add the return type to the signature where possible, e.g. function foo(): string {}
• When a parameter is typed mixed, look at call sites for a narrower type. If there are multiple plausible options, ask the user.

Fixing "Access to an undefined property" in a Symfony action

Symfony actions set template variables as $this->varName inside action methods, which triggers this PHPStan error. The correct fix is a class PHPDoc declaration:

/**
 * @property string $templateVar
 */
class aboutActions extends sfActions
{
    public function executeIndex(): void
    {
        $this->templateVar = "value";
    }
}
