Some Method Overriding rules :
1. In the overriding, the method names and arguments (argâs) must be same.
Example:
class p { public function getName(){} }
class c extends P{ public function getName(){} }
2. final methods canât be overridden.
3. private methods never participate in the in the overriding because these methods are not visible
in the child classes.
Example:
class a {
private function my(){
print "parent:my";
}
public function getmy(){
$this->my();
}
}
class b extends a{
private function my(){
print "base:my";
}
}
$x = new b();
$x->getmy(); // parent:my
4. While overriding decreasing access specifier is not allowed
class a {
public function my(){
print "parent:my";
}
}
class b extends a{
private function my(){
print "base:my";
}
}
//Fatal error: Access level to b::my() must be public (as in class a)
