To copy base part of derived class appropriate method in base should be defined. E.g.:
class A {
public function setAVar( $oAVar) { $this->oAVar = $oAVar; }
public function getAVar() { return $this->oAVar; }
public function copyA( &$roDest) {
if( $roDest instanceof A)
$this->oAVar = $roDest->oAVar;
}
private $oAVar;
}
class B extends A {
public function setBVar( $oBVar) { $this->oBVar = $oBVar; }
public function getBVar() { return $this->oBVar; }
private $oBVar;
}
$oA = new A();
$oB = new B();
$oA->setAVar( 4);
$oB->setAVar( 5);
$oB->setBVar( 6);
echo "oA::oAVar " . $oA->getAVar() . "<br>";
echo "oB::oAVar " . $oB->getAVar() . "<br>";
echo "oB::oBVar " . $oB->getBVar() . "<br>";
echo "<br>";
$oB->copyA( $oA);
echo "oA::oAVar " . $oA->getAVar() . "<br>";
echo "oB::oAVar " . $oB->getAVar() . "<br>";
echo "oB::oBVar " . $oB->getBVar() . "<br>";
Output:
oA::oAVar 4
oB::oAVar 5
oB::oBVar 6
oA::oAVar 4
oB::oAVar 4
oB::oBVar 6
