Doubts about variables and methods in the {{}} in HTML

I am a website art, used to learn some ASP. Now the company's website is PHP, and now I want to modify some of the features of the site, but the code in the HTML really makes me wonder, never touched this type before. The code is as follows:


{{include file= ' header.html '}}

{{if $cat. parentid>0}}

{{ffcategory catid= $cat. ParentID To=cate}}

{{Else}}

{{ffcategory catid= $cat. CatID to=cate}}

{{/if}}





{{Ffposition}}

{{ffpagelist field= "Jiaoling,address,price1,price2" To= "DataList" order= "' sort ' asc, ' create_time ' desc '}}

• Under current conditions there is {{$datalist. Count}} to get a map of driving schools nearby >

{{ffpagelist pagesize=9 to= "Newsdata" field= "ZHICHI,RENSHU,TGL" order= "' sort ' asc, ' create_time ' desc '}}

{{foreach from= $newsdata. Info item=b Key=k}}

  Number of coaches

  Pass Rate

  
  
  {{$b. tgl}}%
  
  
  
  
  
  


{{/foreach}}

{{$newsdata. Pages}}



{{include file= ' footer.html '}}




I want to know where $b is defined in {{}}. How and where did it come from, the whole code was not accounted for?

It is not visible from the template file where the corresponding PHP file is.
