我想对目录中的一组文件夹执行RecursiveDirectoryIterator,比如./temp
,然后根据文件夹的名称列出每个文件夹中的文件。
例如,我有文件夹A
和B
。
在A中,我有一个文件列表,例如1.txt
,2.php
,2.pdf
,3.doc
,3.pdf
。
在B中,我有1.pdf
,1.jpg
,2.png
。
我希望我的结果是这样的:
A => List of files in A
B => List of files in B
如何做到这一点?
<?php
$scan_it = new RecursiveDirectoryIterator("./temp");
foreach(new RecursiveIteratorIterator($scan_it) as $file =>$key) {
$filetypes = array("pdf");
$filetype = pathinfo($file, PATHINFO_EXTENSION);
if (in_array(strtolower($filetype), $filetypes)) {
$dlist=basename($file); //sort
?>
<ul>
<li>
<?php echo substr(dirname($file),11);?>
</li>
<li>
<a href="<?php echo $file;?>"><?php echo basename($file);?></a>
</li>
</ul>
<?php
}}
?>

使用RecursiveDirectoryIterator
和RecursiveIteratorIterator
的组合来遍历所有子目录。
下面的代码片段可以满足你的需要,虽然它仅限于创建一个数组深度的数组...这是为了避免陷入递归混乱,在一个已经混淆到程序化的大脑中的小片段
$array = array();
foreach ($iterator = new RecursiveIteratorIterator(
new RecursiveDirectoryIterator("./temp",
RecursiveDirectoryIterator::SKIP_DOTS),
RecursiveIteratorIterator::SELF_FIRST) as $item) {
// Note SELF_FIRST, so array keys are in place before values are pushed.
$subPath = $iterator->getSubPathName();
if($item->isDir()) {
// Create a new array key of the current directory name.
$array[$subPath] = array();
}
else {
// Add a new element to the array of the current file name.
$array[$subPath][] = $subPath;
}
}
}

//Managed to put this together and it somehow works for me. If you have other options please provide. Thanks
$path='./temp';
$dir = new RecursiveDirectoryIterator($path, RecursiveDirectoryIterator::SKIP_DOTS);
$files = new RecursiveIteratorIterator($dir, RecursiveIteratorIterator::CHILD_FIRST);
foreach ($files as $file=>$mykey) {
if(is_dir($file)) {
$directory = $file;
$mydir = new RecursiveIteratorIterator(new RecursiveRegexIterator(new RecursiveDirectoryIterator($directory,RecursiveDirectoryIterator::FOLLOW_SYMLINKS),
// match both pdf file extensions and directories
'#(?<!/)\.pdf$|^[^\.]*$#i'),true);
foreach ($mydir as $myfile=>$mykey) {
$result[] = $myfile.'<br />';
$filetypes = array("pdf");
$filetype = pathinfo($myfile, PATHINFO_EXTENSION);
if (in_array(strtolower($filetype), $filetypes)) {
// output all matches substr(dirname($file),11)
?>
<div><h3<?php echo count($result);?>>
<span><?php echo substr(PHP_EOL . $directory . PHP_EOL . PHP_EOL,13);?></span></h3></div>
<?php if (!empty($mydir)) {
foreach ($mydir as $d) {
if (strpos($d->getFilename(), '.pdf') !== FALSE) {?>
<div><ul><li><a href="<?php echo $d;?>"><?php echo basename($d->getPath() . DIRECTORY_SEPARATOR . $d->getFilename() . PHP_EOL);?></a></li></ul></div>
<?php }
}
}
}
}
}
}

我认为你需要的是scandir功能。该链接显示了此功能的文档。
