Question

我目前正在对PHP中的foreach循环进行练习，我想使用bootstrap并在我的PHP中的列表项中添加一个类。

<?php
$groceries = array("eggs", "milk", "bread", "apples", "bananas", "fruit rollups", "steak", "kale", "pasta", "flour", "sugar", "vanilla");
?>

<!DOCTYPE html>
<html>
<head>
    <link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.1/css/bootstrap.min.css">
    <title>Array Practice</title>
</head>
<body>
    <div class="container">
    <h1>My Grocery List</h1>
    <ul class="list-group">
        <?php
            foreach ($groceries as $purchase) {
            echo "<li class="list-group-item">" . $purchase . "</li>";
        }
        ?>
    </ul>
    </div>
</body>
</html>

Answer 1

替换以下内容：

echo "<li class="list-group-item">" . $purchase . "</li>";

通过：

echo '<li class="list-group-item">' . $purchase . "</li>";

如何将类名添加到嵌套在PHP中的HTML <li>？
