关于smarty的is_cached()方法的问题请大神帮忙.万分感激.

';  <br>var_dump($smarty);  <br>echo'<pre class="brush:php;toolbar:false">';  <br>得的结果是以下,  <br>object(Smarty)#1 (65) {  <br>  ["auto_literal"]=>  <br>  bool(true)  <br>  ["error_unassigned"]=>  <br>  bool(false)  <br>  ["use_include_path"]=>  <br>  bool(false)  <br>  ["template_dir":"Smarty":private]=>  <br>  array(1) {  <br>    [0]=>  <br>    string(42) "/usr/local/apache2/htdocs/www/smarty/temp/"  <br>  }  <br>  ["_joined_template_dir"]=>  <br>  string(42) "/usr/local/apache2/htdocs/www/smarty/temp/"  <br>  ["_joined_config_dir"]=>  <br>  string(44) "/usr/local/apache2/htdocs/www/smarty/configs"  <br>  ["default_template_handler_func"]=>  <br>  NULL  <br>  ["default_config_handler_func"]=>  <br>  NULL  <br>  ["default_plugin_handler_func"]=>  <br>  NULL  <br>  ["compile_dir":"Smarty":private]=>  <br>  string(41) "/usr/local/apache2/htdocs/www/smarty/com/"  <br>  ["plugins_dir":"Smarty":private]=>  <br>  NULL  <br>  ["cache_dir":"Smarty":private]=>  <br>  string(43) "/usr/local/apache2/htdocs/www/smarty/cache/"  <br>  ["config_dir":"Smarty":private]=>  <br>  array(1) {  <br>    [0]=>  <br>    string(44) "/usr/local/apache2/htdocs/www/smarty/configs"  <br>  }  <br>  ["force_compile"]=>  <br>  bool(false)  <br>  ["compile_check"]=>  <br>  bool(true)  <br>  ["use_sub_dirs"]=>  <br>  bool(false)  <br>  ["allow_ambiguous_resources"]=>  <br>  bool(false)  <br>  ["merge_compiled_includes"]=>  <br>  bool(false)  <br>  ["force_cache"]=>  <br>  bool(false)  <br>  ["left_delimiter"]=>  <br>  string(2) "  ["right_delimiter"]=>  <br>  string(2) "}>"  <br>  ["security_class"]=>  <br>  string(15) "Smarty_Security"  <br>  ["security_policy"]=>  <br>  NULL  <br>  ["php_handling"]=>  <br>  int(0)  <br>  ["allow_php_templates"]=>  <br>  bool(false)  <br>  ["debugging"]=>  <br>  bool(false)  <br>  ["debugging_ctrl"]=>  <br>  string(4) "NONE"  <br>  ["smarty_debug_id"]=>  <br>  string(12) "SMARTY_DEBUG"  <br>  ["debug_tpl"]=>  <br>  NULL  <br>  ["error_reporting"]=>  <br>  NULL  <br>  ["config_overwrite"]=>  <br>  bool(true)  <br>  ["config_booleanize"]=>  <br>  bool(true)  <br>  ["config_read_hidden"]=>  <br>  bool(false)  <br>  ["compile_locking"]=>  <br>  bool(true)  <br>  ["cache_locking"]=>  <br>  bool(false)  <br>  ["locking_timeout"]=>  <br>  int(10)  <br>  ["default_resource_type"]=>  <br>  string(4) "file"  <br>  ["caching_type"]=>  <br>  string(4) "file"  <br>  ["default_config_type"]=>  <br>  string(4) "file"  <br>  ["resource_cache_mode"]=>  <br>  int(1)  <br>  ["cache_modified_check"]=>  <br>  bool(false)  <br>  ["registered_plugins"]=>  <br>  array(0) {  <br>  }  <br>  ["registered_objects"]=>  <br>  array(0) {  <br>  }  <br>  ["registered_classes"]=>  <br>  array(0) {  <br>  }  <br>  ["registered_filters"]=>  <br>  array(0) {  <br>  }  <br>  ["registered_resources"]=>  <br>  array(0) {  <br>  }  <br>  ["registered_cache_resources"]=>  <br>  array(0) {  <br>  }  <br>  ["autoload_filters"]=>  <br>  array(0) {  <br>  }  <br>  ["default_modifiers"]=>  <br>  array(0) {  <br>  }  <br>  ["escape_html"]=>  <br>  bool(false)  <br>  ["start_time"]=>  <br>  float(1461252359.6399)  <br>  ["_current_file"]=>  <br>  NULL  <br>  ["_parserdebug"]=>  <br>  bool(false)  <br>  ["_objType"]=>  <br>  int(1)  <br>  ["_debug"]=>  <br>  NULL  <br>  ["cache_id"]=>  <br>  NULL  <br>  ["compile_id"]=>  <br>  NULL  <br>  ["caching"]=>  <br>  int(1)  <br>  ["cache_lifetime"]=>  <br>  int(3600)  <br>  ["_cache"]=>  <br>  array(6) {  <br>    ["template_dir_new"]=>  <br>    bool(true)  <br>    ["template_dir"]=>  <br>    bool(false)  <br>    ["compile_dir"]=>  <br>    bool(true)  <br>    ["config_dir_new"]=>  <br>    bool(true)  <br>    ["config_dir"]=>  <br>    bool(false)  <br>    ["cache_dir"]=>  <br>    bool(true)  <br>  }  <br>  ["template_class"]=>  <br>  string(24) "Smarty_Internal_Template"  <br>  ["tpl_vars"]=>  <br>  array(0) {  <br>  }  <br>  ["parent"]=>  <br>  NULL  <br>  ["config_vars"]=>  <br>  array(0) {  <br>  }  <br>  ["ext"]=>  <br>  object(Smarty_Internal_Extension_Handler)#2 (3) {  <br>    ["objType"]=>  <br>    int(1)  <br>    ["_property_info":"Smarty_Internal_Extension_Handler":private]=>  <br>    array(7) {  <br>      ["AutoloadFilters"]=>  <br>      int(0)  <br>      ["DefaultModifiers"]=>  <br>      int(0)  <br>      ["ConfigVars"]=>  <br>      int(0)  <br>      ["DebugTemplate"]=>  <br>      int(0)  <br>      ["RegisteredObject"]=>  <br>      int(0)  <br>      ["StreamVariable"]=>  <br>      int(0)  <br>      ["TemplateVars"]=>  <br>      int(0)  <br>    }  <br>    ["resolvedProperties":"Smarty_Internal_Extension_Handler":private]=>  <br>    array(0) {  <br>    }  <br>  }  <br>}  <br>没有is_cached()此方法,我问题要问的是,如果没有is_cached()这个方法,哪用什么方法来代替?不胜感谢...  <br>  <p class="sougouAnswer">  谢谢二楼，已经搞掂。。。。 </p>
