thinkphp Data Template display-system variables, constants, configuration files

Second, the system variable output

Normal template variables need to be assigned first to output in the template, but the system variables do not need to be directly in the template output, the output of system variables usually start with {$Think, eg:

{$Think. Server.script_name}   Output $_server[' script_name '] variable {$Think. session.user_id}      //Output $_session[' user_id '] variable {$Think. Get.pagenumber}       //Output $_get[' pagenumber '] variable {$Think. cookie.name}          //Output $_cookie[' name '] variable

Support Output $_server, $_env, $_post, $_get, $_request, $_sessioin and $_cookie variables

Three, constant output

1. System Constants

Output constants: {$Think. Const.module_name} or: {$Think. module_name}

? 2. Customize the constants in the controller and output

Controller: Const PAI = 3.14;  $this->assign ("Pai", Self::P ai); $this->display (); Template: {$pai}

Iv. Configuration Output

First, there is a definition in the configuration file in which the output can be called directly in the template file

Output configuration parameters: {$Think. config.db_charset}      {$Think. Config.url_model}

? ? Five, language output

Output language variable: {$Think. lang.page_error}      {$Think. Lang.var_error}
