Inherited static properties refer to the same value across classes:
|
|
string(8) "original"
|
|
string(8) "original"
|
|
string(8) "original"
|
|
|
|
Changing one changes all the others:
|
|
string(11) "changed.all"
|
|
string(11) "changed.all"
|
|
string(11) "changed.all"
|
|
|
|
But because this is implemented using PHP references, the reference set can easily be split:
|
|
string(11) "changed.all"
|
|
string(11) "changed.one"
|
|
string(11) "changed.all"
|
|
