<?php

{
????private?static?$c?=?0;
????/**

//?Print?out?basic?information
printf(
????"===>?The?%s%s%s%s%s%s%s?method?'%s'?(which?is?%s)\n"?.

????"?????having?the?modifiers?%d[%s]\n",
????????$method->isInternal()???'internal'?:?'user-defined',
????????$method->isAbstract()???'?abstract'?:?'',
????????$method->isFinal()???'?final'?:?'',
????????$method->isPublic()???'?public'?:?'',

);
//?Print?documentation?comment

//?Print?static?variables?if?existant
if?($statics=?$method->getStaticVariables())?{
????printf("--->?Static?variables:?%s\n",?var_export($statics,?1));
}
//?Invoke?the?method
printf("--->?Invocation?results?in:?");
var_dump($method->invoke(NULL));
?>
上面的例子会输出类似于:
===> The user-defined final public static method 'increment' (which is a regular method)
declared in /Users/philip/cvs/phpdoc/test.php
lines 14 to 17
having the modifiers 261[final public static]
---> Documentation:
'/**
* Increment counter
*
* @final
* @static
* @access public
* @return int
*/'
---> Invocation results in: int(1)
