Thinkphp_ Template system Variable $think

System variable Output

Normal template variables need to be assigned before they can be 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 , for example:

 
   
  
 
    
   
   {  $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
