Question

我需要我的脚本按日期对.txt文件进行排序。它就像一个简单的新闻脚本，我所做的是添加名为：

的.txt文件

[23.7.13]新酷标题 [24.7.13]建议和提示

并回复内容，已准备好一切，包括回声部分但它不会在第一次约会时对它们进行排序..我怎么能这样做？

<?
    if( $handle = opendir( 'includes/news' )) 
    {
        while( $file = readdir( $handle )) 
        {
            if( strstr( $file, "txt" ) )
            {
                $addr = strtr($file, array('.txt' => ''));
                echo '<h1><a href="?module=news&read=' . $addr . '">&raquo;' .
                    $addr . "</a></h1>";
            }
         }
        closedir($handle);
    }
}
?>

$files = array();
$dir = new DirectoryIterator('includes/news');
foreach ($dir as $fileinfo) {     
    $files[$fileinfo->getMTime()] = $fileinfo->getFilename();
}

ksort($files);

编辑:(试试这个）;

<?
$dir = new DirectoryIterator('includes/news');
//$dir = new DirectoryIterator('.');
$num = 0;
foreach ($dir as $fileinfo) {     
$name = $fileinfo->getFilename();
preg_match_all('/\[(.*?)\]/',$string, $matches); 
//preg_match_all('/\-(.*?)\-/',$name, $matches);
if(!empty($matches[1])) {
    //create timestamp (to use for key)
    $timestamp = strtotime($matches[1][0]);
    //use this as array key (to order by with ksort()
    $files[$timestamp]['name'] = $name;
}
}

//sort 
ksort($files);

//get the key back to the normal date 
foreach($files as $key=>$value) {
    $sorted_files[date('d.m.Y',$key)] = $value; 
}

var_dump($files);
?>
