Example #1 ReflectionClass::hasProperty() example
<?php
class Foo {
public $p1;
protected $p2;
private $p3;
}
$obj = new ReflectionObject(new Foo());
var_dump($obj->hasProperty("p1"));
var_dump($obj->hasProperty("p2"));
var_dump($obj->hasProperty("p3"));
var_dump($obj->hasProperty("p4"));
?>
以上例程的输出类似于：
bool(true) bool(true) bool(true) bool(false)
