调用动态方法

Question

Let's suppose that I have a class with a method getWorkDays() that returns an Object. That object has other methods like setMonday($val) , setTuesday($val) ..

What I'm trying to do is to call those methods dynamically:

$weekDays = array('sunday', 'monday', 'tuesday', 'wednesday', 'thursday', 'friday', 'saturday');

foreach($weekDays as $weekDayName){                
    call_user_func($obj->getWorkDays()->set{ucfirst($weekDayName)}, array(1));     
}

Any idea what I'm doing wrong? Or how can I do this?

Thanks in advance

Answer 1

here the code:

$weekDayName = ucfirst($weekDayName);
$obj->set{$weekDayName}();

Answer 2

it seems that you are on right track. you have syntax error in calling set() method. you have missed () in this method calling. it should be something like this:

call_user_func($obj->getWorkDays()->set{ucfirst($weekDayName)}(), array(1));

or you can split it out:

$objFirst = $obj->getWorkDays();
$params = $objFirst->set{ucfirst($weekDayName)}();

call_user_func($params,array(1));

Answer 3

Try this:

$day = ucfirst($weekDayName);
$method = "set{$day}"; 
call_user_func($obj->getWorkDays()->$method, array(1));
