PHP For Loop中的每个第7和第8个表单元格样式

Question

I know you can set every nth row or cell of a table to have certain attributes in a for Loop

   if($ib % 7){
   echo '<td>'.$ib.'</td>';
   }
  else{
  echo '<td bgcolor="005082"></td>';
  }

But can you do the same for the next row aswell. In other words can I set every 7th and 8th table cell next to each other to have the same colour? I'm building a calendar and want to highlight the weekend.

Answer 1

You mean like

if($ib % 7 == 0 || $ib % 7 == 1){
    echo '<td bgcolor="005082"></td>';
}
else {
    echo '<td>'.$ib.'</td>';
}

Answer 2

In case you would achieve it using CSS nth-child

table tr td:nth-child(7n+7), table tr td:nth-child(7n+8) {
    background: #005082;
}

I selected 6th & 7th elements as a week lasts 7 days...
