如何在php中检索文本作为可点击链接？

Question

这是我查看用户帖子的代码，但它将链接显示为普通文本。如何检测 url 并转换为可点击的链接？附上参考：

function get_posts()

{

    global $con;

    $get_posts = "SELECT * FROM posts";

    $run_posts = mysqli_query($con, $get_posts);

    while ($row_posts = mysqli_fetch_array($run_posts)) {

        $post_id = $row_posts['post_id'];

        $user_id = $row_posts['user_id'];

        $content   = $row_posts['post_content'];

        $post_date = $row_posts['post_date'];

        echo "<div class='posts'>

        <p>$post_date</p>

        <p>$content</p>

        <a href='single.php?post_id=$post_id'Style='float:right;'>

        <button>See Replies or Reply to is</button></a>

        </div><br/>";

    }

}

此解决方案将捕获所有 http/https/www 并转换为可点击链接。$url&nbsp;=&nbsp;'~(?:(https?)://([^\s<]+)|(www\.[^\s<]+?\.[^\s<]+))(?<![\.,:])~i';&nbsp; $content&nbsp;=&nbsp;preg_replace($url,&nbsp;'<a&nbsp;href="$0"&nbsp;target="_blank"&nbsp;title="$0">$0</a>',&nbsp;$content);
