Laravel Saving data - laravel-4

Question

In my Laravel project I use this code into controller method to save data:
$countCourseTeacher++;
$routine->p1=Input::get('course_teacher' . $countCourseTeacher);
$routine->p2=Input::get('course_teacher' . $countCourseTeacher);
$routine->p3=Input::get('course_teacher' . $countCourseTeacher);
But I want to use $routine->p$i into a for loop Like
for ($i=1; $i <=6; $i++) {
$countCourseTeacher++;
$routine->p$i=Input::get('course_teacher' . $countCourseTeacher);
}
When I use $routine->p$i
instead of using
$routine->p1 , $routine->p2, $routine->p3.....
It gives error. Is there any way to do this into a forloop using p$i???

Answer 1

That is the normal behaviour in PHP. You can use interpolation. If you want to use interpolation for object properties/methods, use brackets around the string. Here are a quick example:
for ($i=1; $i <=6; $i++) {
$countCourseTeacher++;
$routine->{"p$i"} = Input::get('course_teacher'.$countCourseTeacher);
}

Any Way I find My answer myself. I use thos code below
for ($j=1; $j <=6; $j++) {
$routine=new RoutineCreate;
$routine->configuration_id=$idcnfg;
$routine->day=Input::get('day' . $j);
for ($i=1; $i <=10; $i++) {
$pi="p" . $i;
$countCourseTeacher++;
$routine->$pi=Input::get('course_teacher' . $countCourseTeacher);
}
$routine->save();
