The examples in this article describe the definition and inheritance usage of PHP classes. Share it with everyone for your reference. The details are as follows:

/*
* class
*/
class people {
public $name;
public $age;
function __construct($namec,$agec) {
$this->name = $namec;
$this->age = $agec;
}
protected function getmessage() {
return "Name:".$this->name."
"."Age: ".$this->age;
}
function __tostring() {
return "Name: ".$this->name."
"."Age: ".$this-> age;
}
function __destruct() {
echo "
I am dead!";
}
function __call($key,$args) {
echo "
"," The method name you called does not exist: $key","
";
echo "The parameters you called are:",var_dump($args);
}
final function getf() {
echo " I am getf";
}
}
class xinxin extends people {
function getname() {
echo $this->getmessage();
echo '

echo parent::getmessage( );
echo '

return "I am xinxin";
}
function getmessage() {
return "I am zilei getmessage
";
}
function getff( ) {

}
}
$pp = new people("小哥","33");
//$pp->name = "Xiao Ming";
//$pp ->age = "88";
