读取文件夹中的文件名并使用PHP将它们存储在XML中？

问题描述：

I would like to know how one can write PHP code to read filenames from a particular folder and save the extracted filenames in an XML document?

An example of any part of this would be HIGHLY appreciated.

Thanks

Modify the code example found at readdir() manual a bit, and you're done! Something like this could work:

<?php
$out="<FileList>
";
if ($handle = opendir('.')) {
    while (false !== ($file = readdir($handle))) {
        if ($file != "." && $file != "..") {
            $out.='<file>'.$file."</file>
";
        }
    }
    closedir($handle);
}
$out.='</FileList>';
file_put_contents("./outfile.xml",$out);
?>

Start looking at glob() for reading the filenames of a directory. Work yourself through array-manipulation and look at the file-manipulation functions afterwards: file_put_contents

I would recommend using SimpleXML rather than handcrafting your XML. You don't want your system to choke whenever someone uses special characters in file names.

$out = simplexml_load_string('<files />');

$DI = new DirectoryIterator('/path/to/dir');
foreach ($DI as $file)
{
    if ($file->isFile())
    {
        $out->addChild('file', $file->getFilename());
    }
}

$out->asXML('files.xml');
