fwrite($inF,$start."n");
while( $file = readdir($folder) ) {
     if (($file != '.')&&($file != '..')&&($file != 'index.htm')){
     $result="<entry>n<title>$file</title>n<ref href='$path2$file'/>n<param name='image' value='preview.jpg'/>n</entry>n";

推荐答案

您必须循环目录并使用filemtime获取日期并将其转储到数组中，这是一个有效的脚本，您可以更改$ path，$ xmlfile或arsort()到s​​ort()取决于您的需要...

You have to loop the directory and get the date with filemtime and dump it in an array, here's a working script, you may change $path,$xmlfile or arsort() to sort() depanding on your needs ...

<?php

$xmlfile = "playlist.xml";
$path = "http://".$_SERVER['HTTP_HOST'].dirname($_SERVER['SCRIPT_NAME']). "/musicfolder";
$folder = scandir($path);
$files = array();
foreach($folder as $file){
    if($file == '.' OR $file == '..' OR $file == 'index.htm'){}else{
        $files[$file] = filemtime($path.'/'.$file);
    }
}
arsort($files);

//use asort to sort from old to new

$output="<asx version='3.0'>" . PHP_EOL . "<title>Example ASX playlist</title>";
foreach($files as $file => $date){
$output .= "<entry>" . PHP_EOL . "<title>$file</title>" . PHP_EOL . "<ref href='$path'/>" . PHP_EOL . "<param name='image' value='preview.jpg'/>" . PHP_EOL . "</entry>" . PHP_EOL;
}
$output .= "</asx>";
file_put_contents($xmlfile,$output);
?>
