zhgc

Smarty3 内部几个类的关系如下：

1. class Smarty                   extends Smarty_Internal_TemplateBase
   
2. class Smarty_Internal_Template extends Smarty_Internal_TemplateBase
   
3. abstract class Smarty_Internal_TemplateBase extends Smarty_Internal_Data
   
4. abstract class Smarty_Internal_Data
   
5. 
   
6. class Smarty_Internal_SmartyTemplateCompiler extends Smarty_Internal_TemplateCompilerBase
   
7. abstract class Smarty_Internal_TemplateCompilerBase

1.分析$_tag_stack在哪？
Fatal error: Uncaught --> Smarty: Smarty_Internal_Templatetemplate property '_tag_stack' does not exist.
$_tag_stack定义在Smarty_Internal_TemplateCompilerBase

2. Smarty_Internal_Data的三种存在
Smarty_Internal_Data { /** * This object type (Smarty = 1, template = 2, data = 4)
