使用RecursiveDirectoryIterator按日期排序文件 [英] Sort files by date latest at top Using RecursiveDirectoryIterator

问题描述

现在默认情况下，它的字母表显示我不想这样。我想通过使用 RecursiveDirectoryIterator 最新的文件在顶部排序文件。按降序排列

如果条件比较日期&从该日期获得文件

 <？php 
 $ search_path ='D：\xampp \htdocs'; 
 $ file_extension ='php'; 
 $ it = new RecursiveDirectoryIterator（$ search_path）; 
 $ display = Array（$ file_extension）; 
 
 
 foreach（新的RecursiveIteratorIterator（$ it）作为$ 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个'。 $文件 < /跨度><峰; br> 中。 
} 
} 
 
？> 
  

解决方案

我不知道您是否可以通过 DirectoryIterator 你可以直接收集结果，得到时间然后排序，然后呈现它。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（）））; 
 //不需要爆炸时间，只要将它设为日期时间对象
 if（in_array（$ file-> getExtension（），$ display）&& $ amp; time> new DateTime '2014-01-15'））{//是PHP并且大于jan 15 2014 
 $ data [] = array（'filename'=> $ file-> getPathname（），'time' => $ time-> getTimestamp（））; （$ a 
 
 
 
 
 $ b $ {$，$ b）{//按时间最新
返回$ 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 /> 
; 
} 
  

Right now by default its display by alphabet i don't want that way. I Want to sort files by using RecursiveDirectoryIterator latest files at top. In descending order.

Also use if condition to compare date & get files from that date

   <?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>";
             }
        } 

    ?>

解决方案

I don't know if you can sort thru the DirectoryIterator outright by you could gather the results first, get the time then sort that then present it. Example:

$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/>
    ";
}
