复制代码 代码如下:
class bar
{
public function test() {
$this->testprivate();
$this->testpublic();
}
public function testpublic() {
echo bar::testpublic\n;
}
private function testprivate() {
echo bar::testprivate\n;
}
}
class foo extends bar
{
public function testpublic() {
echo foo::testpublic\n;
}
private function testprivate() {
echo foo::testprivate\n;
}
}
$myfoo = new foo();
$myfoo->test(); // bar::testprivate
// foo::testpublic
为啥第一行会输出bar::testprivate呢？
