PHP 无法获取文件的完整路径

Question

我这样做是为了获取数据库中上传的目录和文件。

<?php
require_once('inc/config.php');
$con = mysqli_connect($host, $user, $pass, $db) or die ('Cannot connect :'.mysqli_error());
$sql = "SELECT * FROM profile_info WHERE username = '" . 
$_SESSION['username'] . "'";
$result = mysqli_query($con,$sql);
$row = mysqli_fetch_array($result);
$resume_name = $row['file_name'];

$resume_location ='resume/'.$resume_name;
$resume_ok = "<a href='".$resume_location."'>Resume</a>";
?>

这会获取简历名称，当我想获取文件名和目录时，它只显示目录而不是文件名，如下所示

localhost:82/resume 而不是这样localhost:82/resume/Jannan.pdf 可能出了什么问题？

Answer 1

在变量中设置站点 URL 并给出包含 href 目录的完整路径

 <?php
    require_once('inc/config.php');
    $con = mysqli_connect($host, $user, $pass, $db) or die ('Cannot connect :'.mysqli_error());

    $SITE_URL =  "http://localhost:82/";

    $sql = "SELECT * FROM profile_info WHERE username = '" . $_SESSION['username'] . "'";
    $result = mysqli_query($con,$sql);
    $row = mysqli_fetch_array($result);
    $resume_name = $row['file_name'];

    $resume_location = $SITE_URL.'resume/'.$resume_name;
    $resume_ok = "<a href='".$resume_location."'>Resume</a>";

    ?>
