I need to fill a 10x10 html table using php code with a random number from 1-10 rand(1,10), then depending on the result paint the cell red if <5 or green if >5. i manually created 10 rows with 10 td each and inside I put echo(rand(1,10)) for each one of them but my syntax is wrong and it looks gross

<table>
    <tbody>
        <?php for ($i = 0; $i < 10; $i++) : ?>
            <tr>
                <?php for ($k = 0; $k < 10; $k++) : ?>
                    <?php $num = rand(1, 10); ?>
                    <td style="color: <?= $num < 5 ? 'red' : 'green'; ?>"><?= $num; ?></td>
                <?php endfor; ?>
            </tr>
        <?php endfor; ?>

  • this almost did the job, I need the table cell be painted not the number itself, also can you do this using if...else statements instead of the 'red' : 'green' options? –  May 02 '19 at 19:28
  • I replaced color with background and it worked, now I only need it be done with if...else statements depending on the inside numbers –  May 02 '19 at 19:31
  • My answer uses `if/else` statements based on the inside numbers. It's just using a ternary `if` instead of the standard `if` format. See: https://stackoverflow.com/questions/1506527/how-do-i-use-the-ternary-operator-in-php-as-a-shorthand-for-if-else – really_operator May 02 '19 at 19:33
  • can you write only the middle line using classic if...else? –  May 02 '19 at 19:41
  • The equivalent of `= $num < 5 ? 'red' : 'green'; ?>` with a classic `if/else` would be `` I suggest you read this section of the php docs to get a better understanding: https://www.php.net/manual/en/language.operators.comparison.php#language.operators.comparison.ternary And here is a great article explaining the benefits of ternary operators: https://davidwalsh.name/php-shorthand-if-else-ternary-operators – really_operator May 02 '19 at 20:18
