WordPress – How to make a condition in php – display one or another date?

How to make a condition in this construction – display one or another date?

<?php foreach ($items as $k => $v): ?>
            <tr>
                <td><?= $v['number'] ?></td>
                <td><?= $v['date_from'] ?></td>
                <td><?= $v['date_till'] ?></td> 
                <td><?= $v['dealer_title'] ?></td>
                <td><?= $v['producer_title'] ?><?= $v['sys_create'] ?></td>
                <td><?php echo nl2br($v['producer_address']); ?><?php echo nl2br($v['sys_create_address']); ?></td>
                <td><?= nl2br($v['offers_title']) ?><?= nl2br($v['sfera']) ?></td>
                <td><?= $v['status'] ?></td>
            </tr>
        <?php endforeach; ?>

The database has 2 tables: date_till and date_till2.
It is necessary that, if necessary, the date is displayed either from date_till or date_till2.
At the moment, if there is no data in the date_till table, an incorrect date is displayed: 30.11.-0001.
Thanks in advance for any help!

    Th solution would be to use the ternary operator within the PHP code:

    <?php foreach ($items as $k => $v): ?>
    <tr>
        <td><?= $v['number'] ?></td>
        <td><?= $v['date_from'] ?></td>
        <td><?= $v['date_till'] ? $v['date_till'] : $v['date_till2'] ?></td> 
        <td><?= $v['dealer_title'] ?></td>
        <td><?= $v['producer_title'] ?><?= $v['sys_create'] ?></td>
        <td><?php echo nl2br($v['producer_address']); ?><?php echo nl2br($v['sys_create_address']); ?></td>
        <td><?= nl2br($v['offers_title']) ?><?= nl2br($v['sfera']) ?></td>
        <td><?= $v['status'] ?></td>
    </tr>
<?php endforeach; ?>

    Here’s a more readable example with additional testing and secure handling (untested):

    foreach ( $items as $item ) {
    // If date_till is empty, set to date_till2;
    if ( empty( $item['date_till'] ) ) {
        $item['date_till'] = $item['date_till2'];
    }

    // If date_till is still empty, then we've no date: set to "Unknown".
    if ( empty( $item['date_till'] ) ) {
        $item['date_till'] = 'Unknown';
    }

    echo '<tr>';

    printf( '<td>%s</td>', esc_html( $item['number'] ) );
    printf( '<td>%s</td>', esc_html( $item['date_from'] ) );
    printf( '<td>%s</td>', esc_html( $item['date_till'] ) );
    printf( '<td>%s</td>', esc_html( $item['dealer_title'] ) );

    printf( 
        '<td>%s%s</td>', 
        esc_html( $item['producer_title'] ), 
        esc_html( $item['sys_create'] ) 
    );

    printf( 
        '<td>%s%s</td>', 
        nl2br( esc_html( $item['producer_address'] ) ), 
        nl2br( esc_html( $item['sys_create_address'] ) ) 
    );

    printf(
        '<td>%s%s</td>',
        nl2br( esc_html( $item['offers_title'] ) ),
        nl2br( esc_html( $item['sfera'] ) )
    );

    printf( '<td>%s</td>', esc_html( $item['status'] ) );

    echo '</tr>';
}

    Ternary operators are valuable for their conciseness, which in some cases is more readable, but in most cases reduces readability.
