Using an oject reference directly return from a function call

[johnwarde]

Hi,

 

I am trying to use an object reference directly from a function call (that returns the object reference):

echo $objTestB->getObj()->getVal();

 

See code for full example.

 

class TestA {
    var $_strTest = 'Hello World!';
    function getVal() {
        return $this->_strTest;
    }
}

class  TestB {
    var $_objTestA = NULL;
    function TestB() {
        $this->_objTestA = new TestA;
    }
    function &getObj() {
        return $this->_objTestA;
    }
}


$objTestB = new TestB;

$refTestA = $objTestB->getObj();
echo $refTestA->getVal();
// I know the above 2 lines work, but I want to do it in one line like this...
echo $objTestB->getObj()->getVal();

 

Thanks for your help,

 

JB

I do not think that is possible with PHP. I know it is in like VB .NET and other language but I have yet to figure it out in PHP.
