How to display each row with a different color

I am new to PHP and I want to display a table from my database with each row with a different color from other rows and I tried answers and solutions similar to my question but I failed to make it done on the rows of <td><?= $field ?></td>

This my script :

<?php
mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);
$mysqli = mysqli_connect('localhost','root','','class');
$mysqli->query("set names 'UTF8'");

$data = [];
$res = $mysqli->query("SELECT math, physics, english FROM student order by math desc");
while ($row = $res->fetch_assoc()) {
    foreach(array_keys($row) as $key) {
        $data[$key][] = $row[$key];
    }
}

?>

<div>student</div>
<table border="1">
  <?php foreach($data as $key => $val): ?>
    <tr>
      <td><?= $key ?></td>
      <?php foreach($val as $field): ?>
        <td><?= $field ?></td>
      <?php endforeach ?>
    </tr>
  <?php endforeach ?>
</table>

You can do this with the help of CSS

For even and odd selectors you follow following syntax

table tr:nth-child(even) td{
   background: #f1f1f1;
}
table tr:nth-child(odd) td{
   background: #fff;
}

I'm just using the following function as an example which returns a random color. The function has been posted by @outis

function rand_color() {
  return '#' . str_pad(dechex(mt_rand(0, 0xFFFFFF)), 6, '0', STR_PAD_LEFT);
}

This will return a random RGB hex string which you can use in your foreach loop, like this (note the <tr> tag): 

<div>student</div>
 <table border="1">
   <?php foreach($data as $key => $val): ?>
   echo '<tr style="background-color:' . rand_color() .   '">';
     <td><?= $key ?></td>
      <?php foreach($val as $field): ?>
     <td><?= $field ?></td>
   <?php endforeach ?>
   </tr>
   <?php endforeach ?>
 </table>
</div>

If you just want to use specifiek colors, then i suggest to define those colors in an array, and then use those as you loop through your data.
