我正在尝试创建一个简单的产品目录网站，我想为每个产品显示卡片。我试图通过 PHP 模板变量显示卡片，并将名称、img src、价格等作为参数传递给打印卡片的函数。这是我的index.php代码：<?phprequire('./php/product_card.php');?><!DOCTYPE html><html><head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <!-- index.css link ref --> <link rel="stylesheet" href="css/index.css"> <!-- Bootstrap Link Tag --> <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" integrity="sha384-JcKb8q3iqJ61gNV9KGb8thSsNjpSL0n8PARn9HuZOnIxN0hoP+VmmDGMN5t9UJ0Z" crossorigin="anonymous"> <!-- FontAwesome Link Tag --> <link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.14.0/css/brands.min.css" integrity="sha512-AMDXrE+qaoUHsd0DXQJr5dL4m5xmpkGLxXZQik2TvR2VCVKT/XRPQ4e/LTnwl84mCv+eFm92UG6ErWDtGM/Q5Q==" crossorigin="anonymous" /> <title>Emmaarz</title></head><body> <div class="container"> <div class="row text-center py-6 mt-5"> <?php product_card("Bed Cover 1", "img_bc/1.jpeg", "Product Description in less than 100 characters (optional)", "399", "299"); product_card("Bed Cover 2", "img_bc/2.jpeg", "Product Description in less than 100 characters (optional)", "599", "399"); ?> </div> </div></body><script src="https://code.jquery.com/jquery-3.5.1.slim.min.js" integrity="sha384-DfXdz2htPH0lsSSs5nCTpuj/zy4C+OGpamoFVy38MVBnE+IbbVYUew+OrCXaRkfj" crossorigin="anonymous"></script><script src="https://cdn.jsdelivr.net/npm/popper.js@1.16.1/dist/umd/popper.min.js" integrity="sha384-9/reFTGAW83EW2RDu2S0VKaIzap3H66lZH81PoYlFhbGU+6BZp6G7niu735Sk7lN" crossorigin="anonymous"></script><script src="https://stackpath.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js" integrity="sha384-B4gt1jrGC7Jh4AgTPSdUtOBvfO8shuf57BaghqFfPlYxofvL8/KUEfYiJOMMV+rV" crossorigin="anonymous"></script></html>当我只是 echo $prod_name; 时 它显示了我传递的产品的名称，但它在 $prod_card 变量中不起作用。看起来是什么问题？如何才能实现这一点呢？

就这样吧。您的变量被视为普通文本字符。您需要将 PHP 变量附加到 HTML 字符串中
<?php
function product_card($prod_name, $prod_img, $prod_desc, $prod_price, $prod_price_disc) {
$prod_card = '
<div class="col-md-3 col-sm-6 my-3 my-md-1">
<form action="index.php" method="get">
<div class="card">
<div>
<img src="$prod_img" alt="error" class=" img-fluid card-img-top">
</div>
<div class="card-body">
<h5 class="card-title">'.
$prod_name.'
</h5>
<p class="card-text">'.
$prod_desc.'
</p>
<h5><s class="text-secondary">'.$prod_price_disc.'</s><span class="mx-2"></span><span class="price">'.$prod_price.'</span></h5>
</div>
</div>
</form>
</div>
';
echo $prod_card;
}
?>

您必须将字符串与变量连接起来，例如 Echo 'fix string'.$var; 在您的情况下，在每个 var $prod_img, $prod_name 之前以 ' 和 add 结束。
在你的情况下 <img src="'.$prod_img.'" 等等
