Is it a php bug?

[Yarco]

PHP Code:
<?php
abstract class testA
{
protected $v;

public function doSet($v)
{
return $this->v = $v;
}
}

abstract class testB extends testA
{
public function doSet($v)
{
parent::doSet($v);
}
}

class testC extends testB
{
}

class testD extends testA
{
}

$c = new testC;
$d = new testD;

print "testC result: ".$c->doSet("CCCCCCCCCCCC")."\n";
print "testD result: ".$d->doSet("DDDDDDDDDDDD")."\n";

?>

Running Result:
testC result:
testD result: DDDDDDDDDDD

Expect Result:
testC result: CCCCCCCCCCC
testD result: DDDDDDDDDDD

No, it's a bug in your code. The doSet() method in testB doesn't
return the value, it only calls the parent function. If you changed
it to:

return parent::doSet($v);

then you'll get the result you were expecting.

Method testB::doSet does not return a value.

Yarco kirjoitti:

PHP Code:
<?php
abstract class testA
{
protected $v;

public function doSet($v)
{
return $this->v = $v;
}
}

abstract class testB extends testA
{
public function doSet($v)
{
parent::doSet($v);

The error is here. It returns nothing. Try

return parent::doSet($v);

}
}

It's not a bug, the result is absolutely correct. The code just doesn't
do what you expect it to do.
