The output content of the above called Database, fourth You need to add class = "last" and how to modify the following php code so that he can add class = "last" at the fourth time"

  ??$arr=explode("|",$_MODULE[linknamea]);
??$arrlink=explode("|",$_MODULE[linka]);
??for($t = 0; $t 
  
????????
??????echo '
'.$arr[$t].'
';
??????}??

  $ Arr = explode ("

$ Arrlink = explode ("

If ($ t = 3 ){
Echo'
  
   
'. $ Arr [$ t].''; Continue;
   
}
   
Echo'
   
'. $ Arr [$ t].'
';
   
}
   
?>
