Calling a method, using a property

Question

For a project I'm working on, I'm trying to call a method using a property

$this->action = "home";
$action = $this->action;
$this->$action();

Is there a shorter way to do this? I tried the following, but it won't work:

$this->action = "home";
$this->$this->action();

So I want to set the $action property, and then call the method that has the same name as $action.

This is probably what you want:

$this->action = "home";
$this->{$this->action}();

This works with methods and properties. $objref->{ [expression] } is the same as $objref->hello if the [expression] evaluates to hello.

Look into the call_user_func function.

Untested, but it may look something like this:

call_user_func($this->action);

call_user_func(array($this,$this->action)); surely

This could work too. If you want to call an instance method you have to supply an array with the object instance too (see callbacks for more on that). That would look like call_user_func(array($this, $this->action));
