How do typehint a parameter of a function in php-CodePudding

I am having issue getting the return type for this function as I have mixed types in the switch. I have used mixed, it blew up. I have used string|bool and several type for union type.

* @param  $value 
* @param  string $type

public function __construct(string $type,  $value)
    {  
        $this->type    = $type;
        $this->value   = $value;
    }

I have tried everything but it didn't pass the CI/CD pipeline (AWS)

public function getValue(bool $typed = false)
    {
        if (false === $typed) {
            return $this->value;
        }

        switch ($this->type) {
            case 'boolean':
                return (bool) $this->value;
            case 'datetime':
                if (empty($this->value)) {
                    return null;
                }

                return new \DateTime($this->value);
            case 'option_tags':
                return json_decode($this->value);
            default:
                return $this->value;
        }
    }

ERROR The following are the error

  Method App\Model\Resources::getValue() has no return typehint specified.  
  Parameter #1 $time of class DateTime constructor expects string, string|true given.                                 
  Parameter #1 $json of function json_decode expects string, bool|string given.

CodePudding user response：

This ERROR is because you didn't declare the type that you want to return from getValue()

This is how you declare the return type

public function getValue(bool $typed = false): date

CodePudding user response：

You need to declare the return type to the function.

Simply to declare a return type, you need to put a : after the params, like this

public function store(Request $request): JsonResponse
