PHP5 includes a complete <a href="http://uk.php.net/manual/en/book.reflection.php" rel="noreferrer">Reflection API</a> for going beyond what the older <a href="http://uk.php.net/manual/en/function.get-class-methods.php" rel="noreferrer">get_class_methods</a> and <a href="http://uk.php.net/manual/en/function.get-object-vars.php" rel="noreferrer">get_object_vars</a> can do.

blocks|key|5761885|text|您可以使用反射API的ReflectionClass::getProperties和ReflectionClass::getMethods方法来实现这一点(尽管该API似乎没有很好的文档记录)。请注意，PHP反射仅反映编译时信息，而不反映运行时对象。如果希望运行时对象也包含在查询结果中，最好使用get_object_vars、get_class_vars和get_class_methods函数。get_object_vars和get_class_vars之间的区别在于，前者获得给定对象上的所有变量(包括在运行时动态添加的变量)，而后者只提供那些在类中显式声明的变量。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|5761886|entityMap|0|LINK|mutability|MUTABLE|url|http://uk.php.net/manual/en/reflectionclass.getproperties.php|1|http://uk.php.net/manual/en/reflectionclass.getmethods.php|2|http://uk.php.net/manual/en/function.get-object-vars.php|3|http://www.php.net/manual/en/function.get-class-vars.php|4|http://www.php.net/manual/en/function.get-class-methods.php^0|B|U|16|R|44|F|4K|E|4Z|H|5J|F|5Z|E|B|U|0|16|R|1|44|F|2|4K|E|3|4Z|H|4|0^^$0|@$1|2|3|4|5|6|7|V|8|@$9|W|A|X|B|C]|$9|Y|A|Z|B|C]|$9|10|A|11|B|C]|$9|12|A|13|B|C]|$9|14|A|15|B|C]|$9|16|A|17|B|C]|$9|18|A|19|B|C]]|D|@$9|1A|A|1B|1|1C]|$9|1D|A|1E|1|1F]|$9|1G|A|1H|1|1I]|$9|1J|A|1K|1|1L]|$9|1M|A|1N|1|1O]]|E|$]]|$1|F|3|-4|5|6|7|1P|8|@]|D|@]|E|$]]]|G|$H|$5|I|J|K|E|$L|M]]|N|$5|I|J|K|E|$L|O]]|P|$5|I|J|K|E|$L|Q]]|R|$5|I|J|K|E|$L|S]]|T|$5|I|J|K|E|$L|U]]]]

You can use the Reflection API's <a href="http://uk.php.net/manual/en/reflectionclass.getproperties.php" rel="noreferrer"><code>ReflectionClass::getProperties</code></a> and <a href="http://uk.php.net/manual/en/reflectionclass.getmethods.php" rel="noreferrer"><code>ReflectionClass::getMethods</code></a> methods to do this (although the API doesn't seem to be very well documented). Note that PHP reflection only reflects compile time information, not runtime objects. If you want runtime objects to also be included in your query results, best to use the <a href="http://uk.php.net/manual/en/function.get-object-vars.php" rel="noreferrer"><code>get_object_vars</code></a>, <a href="http://www.php.net/manual/en/function.get-class-vars.php" rel="noreferrer"><code>get_class_vars</code></a> and <a href="http://www.php.net/manual/en/function.get-class-methods.php" rel="noreferrer"><code>get_class_methods</code></a> functions. The difference between <code>get_object_vars</code> and <code>get_class_vars</code> is that the former gets you all the variables on a given object (including those dynamically added at runtime), while the latter gives you only those which have been explicitly declared in the class.

blocks|key|4344856|text|如果你想更深入，并获得对象的私有变量，你可以使用闭包。像这样：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4344857|$sweetsThief+=+function+($obj)+{

$sweetsThief+=+\Closure::bind($sweetsThief,+null,+$myobj);

If you want to go deeper, and also get the private var of the object, you can use closure for that. like:

<pre><code>$sweetsThief = function ($obj) {
 return get_object_vars($obj);
};

$sweetsThief = \Closure::bind($sweetsThief, null, $myobj);

var_dump($sweetsThief($myobj));
</code></pre>

Is there a function to list all object's public methods and properties in PHP similar to Python's <code>dir()</code>?
