将循环增加2并循环进入循环

Question

我有一个像下面这样的HTML标记-

<div class="f_product_slider slick">
  <div class="row slider_item">
    <div class="col-lg-5 col-sm-6">
        <div class="item">
            <img src="image/bike/cycle_2.png" alt="">
            <div class="content text-right">
                <a href="product-details.html"><h6>Specialized Sirrus Carbon - 2018</h6></a>
                <p>Slayer Bike Expert</p>
            </div>
        </div>
    </div>
    <div class="col-lg-5 col-sm-6">
        <div class="item item_two">
            <img src="image/bike/cycle_2.png" alt="">
            <div class="content text-right">
                <a href="product-details.html"><h6>Specialized Sirrus Carbon - 2018</h6></a>
                <p>Slayer Bike Expert</p>
            </div>
        </div>
    </div>
</div>
<div class="row slider_item">
    <div class="col-lg-5 col-sm-6">
        <div class="item">
            <img src="image/bike/cycle_2.png" alt="">
            <div class="content text-right">
                <a href="product-details.html"><h6>Specialized Sirrus Carbon - 2018</h6></a>
                <p>Slayer Bike Expert</p>
            </div>
        </div>
    </div>
    <div class="col-lg-5 col-sm-6">
        <div class="item item_two">
            <img src="image/bike/cycle_2.png" alt="">
            <div class="content text-right">
                <a href="product-details.html"><h6>Specialized Sirrus Carbon - 2018</h6></a>
                <p>Slayer Bike Expert</p>
            </div>
        </div>
    </div>
  </div>
</div>

这里，每行项目包含两个项目。这就是说，在循环的每个步骤中呈现的每两个循环项。 我在这里给出此循环的直观示例-

如何使PHP while循环成为可能？ 如果您对这个问题感到困惑，请不要犹豫，向我询问更多详细信息。

使用for：

<div class="f_product_slider slick">
    <?php for($slideCounter = 0; $slideCounter < 2; $slideCounter++) { ?>
    <div class="row slider_item">
        <?php for($colCounter = 0; $colCounter < 2; $colCounter++) { ?>
        <div class="col-lg-5 col-sm-6">
            <div class="item">
                <img src="image/bike/cycle_2.png" alt="">
                <div class="content text-right">
                    <a href="product-details.html"><h6>Specialized Sirrus Carbon - 2018</h6></a>
                    <p>Slayer Bike Expert</p>
                </div>
            </div>
        </div>
        <?php } ?>
    </div>
    <?php } ?>
</div>

使用while：

<div class="f_product_slider slick">
    <?php
        $slideCounter = 0;
        while($slideCounter < 2) {
            $slideCounter++ ?>
    <div class="row slider_item">
        <?php
        $colCounter = 0;
        while($colCounter < 2) {
            $colCounter++ ?>

        <div class="col-lg-5 col-sm-6">
            <div class="item">
                <img src="image/bike/cycle_2.png" alt="">
                <div class="content text-right">
                    <a href="product-details.html"><h6>Specialized Sirrus Carbon - 2018</h6></a>
                    <p>Slayer Bike Expert</p>
                </div>
            </div>
        </div>
        <?php } ?>
    </div>
    <?php } ?>
</div>
