您应该将这两个类封装在一个包含的类中,并提供相关的接口(例如私有变量的setter / getters)
class YourFirstClass {
public $variable;
private $_variable2;
public function setVariable2($a) {
$this->_variable2 = $a;
}
}
class YourSecondClass {
public $variable;
private $_variable2;
public function setVariable2($a) {
$this->_variable2 = $a;
}
}
class ContaingClass {
private $_first;
private $_second;
public function __construct(YourFirstClass $first,YourSecondClass $second) {
$this->_first = $first;
$this->_second = $second;
}
public function doSomething($aa) {
$this->_first->setVariable2($aa);
}
}
研究(谷歌)：“继承的构成”
