我有两个类:
class A {
public function load() {
$var = new some_class();
return $var;
}
}
和
class B extends A {
public function test() {
$this->load();
$var->some_method(); // ERROR : variable "$var" does not exists
}
}
我想从类"B"访问类"A"的局部变量$var，我怎么能做到这一点?
用$this->load();填充$var
class B extends A {
public function test() {
$var = $this->load();
$var->some_method(); // WORKS
}
}
