Question

maybe it s a bug, i m not sure.

为什么我执行这一守则:

<?php

class testReflection implements Serializable {
    public function serialize() {
    }
    public function unserialize($data) {
    }
    public function getData() {
    }
}

class testReflection2 implements arrayaccess {
    public function offsetSet($offset, $value) {
    }
    public function offsetExists($offset) {
    }
    public function offsetUnset($offset) {
    }
    public function offsetGet($offset) {
    }
    public function getData() {
    }
}

$c = new ReflectionClass( testReflection );

foreach ($c->getMethods() as $method) {
  var_dump($method->name);
}
echo  ======================== ;
$c = new ReflectionClass( testReflection2 );

foreach ($c->getMethods() as $method) {
  var_dump($method->name);
}

我得出这一结果:

string(9) "serialize"
string(11) "unserialize"
string(7) "getData"
string(11) "unserialize"
string(9) "serialize"
========================
string(9) "offsetSet"
string(12) "offsetExists"
string(11) "offsetUnset"
string(9) "offsetGet"
string(7) "getData"
string(11) "offsetUnset"
string(9) "offsetSet"
string(9) "offsetGet"
string(12) "offsetExists"

接口中界定的方法似乎有两倍。是不是ug?

看来是反思:植被方法在不同的PHP verions上并不可靠,见user comment。
