[英]Listing image files in folders and subfolders with PHP and sort them by date created
[英]php scandir sort first single files then folders and subfolders
我的“ / templates”文件夹中有以下文件和文件夹:
/templates/folder/contact.html
/templates/folder/index.html
/templates/folder/search.html
/templates/index.html
/templates/music.html
/templates/path/index.html
/templates/path/test.html
/templates/video.html
现在,我想获得首先对单个文件进行排序的列表,
然后是文件夹和子文件夹,我的意思是:
/index.html
/music.html
/video.html
/folder/contact.html
/folder/index.html
/folder/search.html
/path/index.html
/path/test.html
而且我正在使用此代码,但无法弄清楚如何按此顺序对其进行排序。.请帮助
<?php
function listFolderFiles($dir, $parent = ''){
$ffs = scandir($dir);
echo '<ol style="padding:0;">';
foreach($ffs as $ff){
if($ff != '.' && $ff != '..'){
echo '<li>'.$parent.'/'.$ff;
if(is_dir($dir.'/'.$ff)){
listFolderFiles($dir.'/'.$ff, $ff );
}
echo '</li>';
}
}
echo '</ol>';
}
listFolderFiles('templates');
?>
请注意:实际上此代码也一次将子文件夹输出为“空”,例如/folder
以及子文件夹中的内容(不带斜杠): folder/contact.html
但我需要有一个斜杠,例如: /folder/contact.html
并删除“空”子文件夹
如果不需要在那里进行其他字母排序,则可以将目录(而不是递归调用)存储到数组中,并在函数末尾对该数组中的所有元素调用listFolderFiles
。
如果您想使用原始的递归方法-不进行文件名排序(如@peter-vančo所述):
function listFolderFiles($dir, $parent = '')
{
$ffs = scandir($dir);
$subfolders = array();
echo '<ol style="padding:0;">';
foreach($ffs as $ff)
{
if (!is_dir($dir . '/' . $ff))
{
echo '<li>'.$parent.'/'.$ff . '</li>';
}
else if($ff != '.' && $ff != '..')
{
$subfolders[$ff] = $dir.'/'.$ff;
}
}
foreach($subfolders as $ff => $subfolderDir)
{
listFolderFiles($subfolderDir, '/' . $ff);
}
echo '</ol>';
}
这是一个简单的递归迭代器,它将每个项目都拆分为:文件夹和文件:
$MójFolder = __DIR__;
$Pliki = array('Pliki'=>array(), 'Foldery'=>array());
$Foldery = [];
$SkanerKatalogówIPlików = new RecursiveDirectoryIterator($MójFolder, RecursiveDirectoryIterator::SKIP_DOTS);
$SkanujWszystkiePodkatalogi = new RecursiveIteratorIterator($SkanerKatalogówIPlików, RecursiveIteratorIterator::SELF_FIRST);
foreach($SkanujWszystkiePodkatalogi as $WszystkiePlikiIFoldery){
$Ścieżka = str_replace($MójFolder, '', $WszystkiePlikiIFoldery);
if($WszystkiePlikiIFoldery->isDir()){
$Pliki['Foldery'][] = '.' . $Ścieżka .'/';
natcasesort($Pliki['Foldery']);
}elseif($WszystkiePlikiIFoldery->isFile()){
$Pliki['Pliki'][] = $Ścieżka ;
}
}
