使用 RecursiveDirectoryIterator 在顶部按最新日期对文件进行排序

现在默认情况下它按字母表显示，我不希望这样。我想使用以下方式对文件进行排序递归目录迭代器最新文件位于顶部。按降序排列。

还使用if 条件比较日期并获取该日期的文件

   <?php
    $search_path = 'D:\xampp\htdocs';
    $file_extension = 'php';
    $it = new RecursiveDirectoryIterator("$search_path");
    $display = Array ($file_extension);


    foreach(new RecursiveIteratorIterator($it) as $file) {
        $test = Array();
        $test = explode("/",date("m/d/Y",filemtime($file)));
        $year = $test[2];
        $day = $test[1];
        $month = $test[0];


    if (in_array(strtolower(array_pop(explode('.', $file))), $display))
             if(($year >= 2014) && ($month >= 1) && ($day >= 15 )){
                   echo "<span style='color:red;'>";
                   echo "<b  style='color:green;'>".$day.'-'.$month.'-'.$year. '</b> ' . $file."</span><br>";
             }
        } 

    ?>

不知道你能否整理一下DirectoryIterator直接来说，您可以先收集结果，获取时间，然后排序，然后呈现。例子：

$display = array('php');
$files = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($search_path));
$data = array();
foreach($files as $file) {
    $time = DateTime::createFromFormat('U', filemtime($file->getPathname()));
    // no need to explode the time, just make it a datetime object
    if(in_array($file->getExtension(), $display) && $time > new DateTime('2014-01-15')) { // is PHP and is greater than jan 15 2014
        $data[] = array('filename' => $file->getPathname(), 'time' => $time->getTimestamp()); // push inside
    }

}
usort($data, function($a, $b){ // sort by time latest
    return $b['time'] - $a['time'];
});


foreach ($data as $key => $value) {
    $time = date('Y-m-d', $value['time']);
    echo "
        <span style='color: red;'>
            <b style='color: green;'>$time</b>$value[filename]
        </span>
        <br/>
    ";
}
