PHP eco 内锚标记内的图像标记

Question

以下是我的php代码

while ($row = mysqli_fetch_array($return_data)) {

        $id = "ID:".$row['demo_id']."<br>";
        $name = "Name: ".$row['demo_name']."<br>";
        $version = "Version: ".$row['demo_version']."<br>";
        $details = "Details: ".$row['demo_details']."<br>";
        $file = "File Link: ".$row['file']."<br>";
        $new = basename( $row['file'] ); // GET FILE NAME ONLY, GET RID OF PATH.
        '<img src = \"../demo_webpages_project/images/$new"/>';
        echo '<a href = "http://'.$_SERVER["SERVER_NAME"].':8080/demo_webpages_project/images/".$new> Link </a>';

我希望 'link' 将我带到我上传的图片 'file'。

但是由于我将锚标记放在回声中，它假定为 '. $new' 作为文字而不是从 $new 变量中获取值。

我该怎么做才能避免这种情况？

Answer 1

当我遇到这种情况时，我只是将事情分解成这样易于管理的部分。

while ($row = mysqli_fetch_array($return_data)) {

        $id = "ID:".$row['demo_id']."<br>";
        $name = "Name: ".$row['demo_name']."<br>";
        $version = "Version: ".$row['demo_version']."<br>";
        $details = "Details: ".$row['demo_details']."<br>";
        $file = "File Link: ".$row['file']."<br>";
        $new = basename( $row['file'] ); // GET FILE NAME ONLY, GET RID OF PATH.

        echo "<a href='http://{$_SERVER['SERVER_NAME']}:8080/demo_webpages_project/images/$new'>";
        echo "<img src='../demo_webpages_project/images/$new'/>";
        echo '</a>';

您不需要此代码上的端口号或完整的域名，如果您确实使用它，则在移动到真实的实时服务器或从一个域到另一个，当然你喜欢我们其他人会忘记做的事情。

所以试试这个

        echo "<a href='demo_webpages_project/images/$new'>";
        echo "<img src='../demo_webpages_project/images/$new'/>";
        echo '</a>';

Answer 2

试试这条线

        echo '<a href = "http://'.$_SERVER["SERVER_NAME"].':8080/demo_webpages_project/images/'.$new.'"> Link </a>';
