打印while循环(scope）php上面的变量 - print variable above of the while loop (scope) php

print variable above of the while loop (scope) php

本文关键字：变量 php while 循环 scope 打印 | 更新日期: 2023-09-27

是否有任何方法可以在while loop下定义变量并将其打印在while loop 上方

像这个

print $catName
while ($b = mysqli_fetch_assoc($results)) {
$catName = $b['cat'];
}

编辑

$getBooks = $db->prepare('SELECT
    id, cat, instituteId, title, cover, authorName FROM books_library WHERE instituteId=? AND cat=?');
$getList = array();
$getBooks->bind_param('ii', $inId, $cid);
if ($getBooks->execute()) {
    $libResults = $getBooks->get_result();
    $getList[] = $libResults;
    ?>

HTML代码来这里

<h3 class="marginBottom8px margin-top_30px text-bold text-danger"><?php echo catName ?></h3>

然后WHILE循环

while ($book = mysqli_fetch_assoc($libResults)) {
                                $bokId = $book['id'];
                                $bookTitle = $bokId['title'];
                                $catName = $bokId['cat'];
                                $catName = $bokId['cat'];

现在在while loop下我得到了$catName我如何在<h3></h3> 中echo

while块之后，将h3html放入变量中并打印。

$myHtml = '<h3 class="marginBottom8px margin-top_30px text-bold text-danger">' 
    . $catName . '</h3>';
print $myHtml;

不要像那样混合html和php。

我认为这就是基于编辑后的问题

while ($book = mysqli_fetch_assoc($libResults)) {
    echo '<h3>' . $book['cat'] . '</h3>';
}
