我们可以在Codeigniter控制器中创建两个具有相同名称的函数吗？

Question

Is there any way I can create 2 functions in Codeigniter controller where one of the function contains argument and the other doesn't. I am using the below code which is giving me an error.

class example extends CI_Controller {
    function show() {
        #code goes here
    }

   function show($id) {
       #code goes here
    }
}

But it's showing me an error that function name cannot be same.

No, but you can do this:

function show($id = null)
{
    if ($id === null) {
        // $id was not passed
    } else {
        // $id was passed
    }
}
