get_defined_vars() — 返回由所有已定义变量所组成的数组,这个函数在二次开发的时候用起来非常给力；

get_defined_constants();可以返回当前的所有常量

zend的调试也能实现当前页面所有变量的显示；

以下代码示例，我在方维分享系统的这个链接的html里http://localhost/xiebei/admin/index.php?a=login&m=Public加了这样一段话

<?PHP 
var_dump(get_defined_vars());
var_dump(get_defined_constants());
?>

然后view-source:http://localhost/xiebei/admin/index.php?a=login&m=Public 的源码如下
