I would like to know whether there's a way to chain methods on a newly created object in PHP?

Something like:

class Foo {
    public function xyz() { ... return $this; }

$my_foo = new Foo()->xyz();

Anyone know of a way to achieve this?

Accepted Answer

No, when you're using the

new Classname();

syntax, you can't chain a method call off the instantiation. It's a limitation of PHP's syntax. Once an object is instantiated, you can chain away.

One method I've seen used to get around this is a static instantiation method of some kind.

class Foo
    public function xyz()
        echo "Called","\n";
        return $this;

    static public function instantiate()
        return new self();

$a = Foo::instantiate()->xyz();

By wrapping the call to new in a static method, you can instantiate a class with method call, and you're then free to chain off that.
