I read the many files written upstairs.phpLabels are complicated, but they are simple.phpAndhtmlTemplate used in combination, directlyechoThat's all,phpThe code is simple, clear, and easy to understand.

  
";} Else if ($ I % 2 = 0) {echo"
";}Else {echo" category not set yet ";}?>

If ($ I % 2 = 0): echo'
'; Elseif ($ I % 4 = 0): echo'
'; Else: echo' no category yet '; endif;

       
         
  Category not set yet
  

Use PHP alternative syntax

  
'; If ($ I % 4 = 0) echo'
'; Else echo' no category yet ';?>
