PHP: how to make new object of class with name stored in member string?

Question

So I want to do something like this:

$ob = new $this->other_class_name;

but it fails. How can I do it without storing other_class_name in local variable?

Save the name in another variable:

$class = $this->other_class_name;
$ob = new $class;

Try this:

$class = get_class($this->other_class_name);
$ob = new $class;

Isn't $this->other_class_name a string and not an object?

by the info given i thought it was an object of the type 'other_class_name' if it is a string it's even easier

Yes... but if you have already an object, you don't even need to create one from a string. You could use the clone method.
