使用foreach（）创建表

Question

I have following PHP code contain 2 foreachs

echo "<table class='table table-bordered'>";
foreach($resultOld as $key=>$value)
{
    foreach ($value as $key1 => $subjects) {
        $checked = $subjects;
        echo  "<tr><tr class=\"".$subjects."\">$key1
            <input type='checkbox' class=\"".$subjects."\"  value='checked' name=\"".$key1."JAN\" $checked/> </tr>               
           </tr>" ;
    }
}
echo "</table>";

$resultOld is a fetchAll(PDO::FETCH_ASSOC) output and it contains a two dimensional array. $subjects will return 661 words from the database which means the $resultOld array have 661 elements. And after every 12 cells I want to start a new line (tr). That means I need 55 rows in the table. How to achieve this using PHP?

If you want a new row after every 12 records, you need to use a counter and check the count -

$counter = 1;
echo "<table class='table table-bordered'>";
echo "<tr>"; //start the first row
foreach($resultOld as $key=>$value)
{
    foreach ($value as $key1 => $subjects) {

        // if the 13th cell, end last row, and start new row
        if ($counter%12==1){
                      echo "</tr><tr>";}
        $checked = $subjects;
        echo  "<td class=\"".$subjects."\">$key1
            <input type='checkbox' class=\"".$subjects."\"  value='checked' name=\"".$key1."JAN\" $checked/> </td>" ;

        // increase counter
        $counter++;
    }
}
echo "</tr>"; // end last row
echo "</table>";
