大家星期六好!
我有这段php代码显示了特定文件夹中的所有文件。一切都运行良好，并按预期工作。
我只有一个问题，当文件显示时，让我说我想在我的网络浏览器上查看一个特定的文件，我点击该文件，我得到"对象未找到"页面。当我查看URL时，我明白了为什么找不到它，因为URL说:http://localhost/studybuddy/maths.txt
但是math .txt文件在'uploads'文件夹中，所以url必须写:http://localhost/studybuddy/uploads/maths.txt，以显示文件
这是我的代码:
<!doctype html>
<html>
<head>
<meta charset="UTF-8">
<title>Student Notes</title>
<link rel="stylesheet" href="style.css">
<script src=".sorttable.js"></script>
<style>
.upload{
position: absolute;
top: 400px;
right: 800px;
}
</style>
</head>
<body>
<div id="container">
<h1>Student Notes</h1>
<table class="sortable">
<thead>
<tr>
<th>Filename</th>
<th>Type</th>
<th>Size <small>(bytes)</small></th>
<th>Date Modified</th>
</tr>

$filename=strtolower($filename);
//$exts=split("[/\.]", $filename);
$n=count($exts)-1;
$exts=$exts[$n];
return $exts;
}
// Closes directory

我的问题是，我如何将正确的目录作为前缀分配给文件作为属性?
希望我已经给了你足够的信息。
感谢- m
可以替换
$namehref = $dirArray[$index];
$namehref = "uploads/" . $dirArray[$index];
