如何使用PHP继续检查帖子?我有一段代码可以通过并获取所有帖子。当我echo $row['post_message'];
时,我收到所有消息。当我将其设置为像$post = $row['post_message'];
这样的变量时,并且<h2><?php echo $post;?></h2>
我只得到一个结果。这是我的代码
$stmt = $con->prepare("SELECT post_message FROM posts WHERE post_user = :username");
$stmt->bindValue(':username', $username, PDO::PARAM_STR);
$row = $stmt->fetchAll();
$stmt->execute();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$post = $row['post_message'];
}
所以,当我echo
时,我得到I like pie I like pie 2alex likes food
,当我将其存储在变量中时,我得到alex likes food
。有任何想法吗?

您的问题出在while
循环中。您将继续覆盖$post
变量。它应该是:
$posts = array();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)){
$posts[] = $row['post_message'];
}
应返回:
Array (
[0] => I like pie I like pie 2,
[1] => alex likes food
)
这允许你做这样的事情(作为例子):
foreach($posts as $post) {
echo 'The user posted: ' . $post . '<br />';
}
