symfony - PHP: Check whether an integer is in a certain interval or not -

i working on achievement system small online game. achievement entity has 4 attributes:

• id
• earnedby
• earnedon
• progress

the last 1 supposed percentage, meaning number between 0 , 100. in order make sure no numbers greater 100 or smaller 0 saved in database, setter-method looks followed (i using symfony2 / doctrine orm):

public function setprogress($progress)     {         $this->progress = max(min($progress, 100), 0);          return $this;     } 

the important line here max(min($progress, 100), 0).

it works totally fine, wanted ask, if there built-in function in php doing thing, , if doing okay (concerning good-developing style)

you should consider adding constraints on entity the validation component of symfony2.

use symfony\component\validator\constraints assert;  class achievement {    /**     * @assert\range(min=0, max=100)     */     protected progress; } 

the validator service called automatically when example validating forms, can call manually getting validator service, example in controller.

$achievement = new achievement(); $errors = $this->get('validator')->validate($achievement);
