How to print in HTML using PHP a list of ul type items with 3 different types?

I do not know what the difficulty would be, if you want to do it in the usual way, mixing PHP with HTML , use:

<div class="row">
    <?php

    $cores = ['carrot', 'amethyst', 'sunflower'];
    $index_cor = 0;

    $planos = mysqli_query($con, 'SELECT id, name, op1, op2, op3, price FROM plans');

    while (list($id, $name, $ops['0'], $ops['1'], $ops['2'], $price) = mysqli_fetch_array($planos, MYSQLI_NUM)) {

        ?>
        <div class="col-md-4 col-sm-4 col-xs-12">
            <div class="table_three">
                <div class="price_table">
                    <div class="price_table_inner">
                        <div class="price_header color_<?= $cores[$index_cor] ?>">
                            <h3><?= htmlentities($name, ENT_QUOTES | ENT_HTML5, 'UTF8') ?></h3>
                            <p>Para Vovós Cozinheiras Iniciantes</p>
                            <div class="ribbon">HOT</div>
                        </div>
                        <div class="price color_<?= $cores[$index_cor] ?>2">
                            <h1>
                                R$ <?= str_replace($price, '.', ',') ?></h1>
                        </div>
                        <div class="service_list">
                            <ul>
                                <?php
                                foreach ($ops as $op) {
                                    ?>
                                    <li><?= htmlentities($op, ENT_QUOTES | ENT_HTML5, 'UTF8'); ?></li>
                                    <?php
                                }
                                ?>
                            </ul>
                        </div>
                        <form action="login.html" method="POST">
                            <input type="hidden" value="<?= htmlentities($id, ENT_QUOTES | ENT_HTML5, 'UTF8') ?>"
                                   name="plano_selecionado">
                            <input type="submit" value="Investir Agora" name="buy"
                                   class="btn color_<?= $cores[$index_cor] ?>3"/>
                        </form>
                    </div>
                </div>
            </div>
        </div>
        <?php
        $index_cor++;
    }
    ?>
</div>

The phrase ( <p>Para Vovós Cozinheiras Iniciantes</p> ) is missing, this is fixed and there is no such information in the database.

I've only done the first one to see how it would work, the rest you can do alone, my intention is not to do it for you, but it shows you how to do it.

<?php
    $select = "SELECT * FROM plans WHERE idplans=1";
    $verifica = mysqli_query($connect, $select) //Onde $connect é a conexão com banco de dados
    $row = mysqli_fetch_row($verifica); //Define as váriaveis
    $name = $row[1];
    $op1 = $row[2];
    $op2 = $row[3];
    $op3 = $row[4];
    $preço = $row[5]
?>

The answer I marked as correct is perfect. Thanks @Inkeliz. As I use PDO connection I had to adapt, so just to add here to this post, it follows how I did using PDO connection:

   <div class="row">
                        <?php

                        $cores = ['carrot', 'amethyst', 'sunflower'];
                        $index_cor = 0;


                        $planos = $pdo->prepare("SELECT name, subtitle, op1, op2, op3, price, qty_credit FROM plans");
                        $planos->execute();



                        $resultado = $planos->fetchAll();

                   //     $linha = $planos->rowCount();




                    //    print("Deleted $linha rows.\n");

                        foreach($resultado as $mostra){
                            $name = addslashes(strip_tags($mostra['name']));
                            $subtitle = addslashes(strip_tags($mostra['subtitle']));  
                            $op1 = addslashes(strip_tags($mostra['op1']));   
                            $op2 = addslashes(strip_tags($mostra['op2']));
                            $op3 = addslashes(strip_tags($mostra['op3']));
                            $price = addslashes(strip_tags($mostra['price']));   
                            $qty_credit = addslashes(strip_tags($mostra['qty_credit']));   






                    ?>
                            <div class="col-md-4 col-sm-4 col-xs-12">
