如何在PHP中合并两个对象包含函数

Question

class Foo {
    public function sampleA(){
        echo "something ...";
    }
}

class Bar {
    public function sampleB(){
        echo "something ...";
    }
}

$objectA = new Foo();

I want to call $objectA->sampleB() directly, not $objectA->somevariable->sampleB(); How to do this?

Answer 1

One possibility is to simply change the class declaration:

class Foo extends Bar {

The other way around is also possible; it really depends on your use-case. Traits are also a possibility.

trait Bar {
    public function sampleB(){
        echo "something ...";
    }
}

class Foo {
    use Bar;

    public function sampleA(){
        echo "something ...";
    }
}
