需要帮助，我有这个文件结构：
文件（文件夹）.pdf.pdf.doc.doc.doc拉链.zip
index.php
我想在index.php中显示"files"文件夹中的文件，并按类型对它们进行排序。此外，我想这样显示：
对于zip：
<div class="dopobrania_zip">
<a href="file adress">file title</a>
</div>
pdf格式：
<div class="dopobrania_pdf">
<a href="file adress">file title</a>
</div>
对于文档：
<div class="dopobrania">
<a href="file adress">file title</a>
</div>
你能帮我吗？
你应该试试这段代码，也许你能找到出路。
//directory to list, you choose; here we’ll just use the webroot
$path = $_SERVER['DOCUMENT_ROOT'];
//warning: `is_dir` will need you to change to the parent directory of what you are testing
//see <uk3.php.net/manual/en/function.is-dir.php#70005> for details
chdir ($path);
//get a directory listing
$dir = array_diff (scandir ('.'),
//folders / files to ignore
array ('.', '..', '.DS_Store', 'Thumbs.db')
);
//sort folders first, then by type, then alphabetically
usort ($dir, create_function ('$a,$b', '
return is_dir ($a)
? (is_dir ($b) ? strnatcasecmp ($a, $b) : -1)
: (is_dir ($b) ? 1 : (
strcasecmp (pathinfo ($a, PATHINFO_EXTENSION), pathinfo ($b, PATHINFO_EXTENSION)) == 0
? strnatcasecmp ($a, $b)
: strcasecmp (pathinfo ($a, PATHINFO_EXTENSION), pathinfo ($b, PATHINFO_EXTENSION))
))
;
'));
//echo to screen
header ('content-type: text/plain');
print_r ($dir);
