使用PHP递归函数列出目录中的所有文件和文件夹

我正在尝试查看目录中的所有文件，如果有目录，则查看其所有文件，依此类推，直到没有更多目录可供访问.每个处理过的项目都将添加到下面函数中的结果数组中.虽然我不确定我能做什么/我做错了什么，但它不起作用，但是当处理下面的代码时，浏览器运行速度非常慢，感谢任何帮助，谢谢！

I'm trying to go through all of the files in a directory, and if there is a directory, go through all of its files and so on until there are no more directories to go to. Each and every processed item will be added to a results array in the function below. It is not working though I'm not sure what I can do/what I did wrong, but the browser runs insanely slow when this code below is processed, any help is appreciated, thanks!

function getDirContents($dir){ $results = array(); $files = scandir($dir); foreach($files as $key => $value){ if(!is_dir($dir. DIRECTORY_SEPARATOR .$value)){ $results[] = $value; } else if(is_dir($dir. DIRECTORY_SEPARATOR .$value)) { $results[] = $value; getDirContents($dir. DIRECTORY_SEPARATOR .$value); } } } print_r(getDirContents('/xampp/htdocs/WORK'));

推荐答案

获取一个目录下的所有文件和文件夹，有.或...

Get all the files and folders in a directory, don't call function when you have . or ...

<?php function getDirContents($dir, &$results = array()) { $files = scandir($dir); foreach ($files as $key => $value) { $path = realpath($dir . DIRECTORY_SEPARATOR . $value); if (!is_dir($path)) { $results[] = $path; } else if ($value != "." && $value != "..") { getDirContents($path, $results); $results[] = $path; } } return $results; } var_dump(getDirContents('/xampp/htdocs/WORK'));

输出(示例):

array (size=12) 0 => string '/xampp/htdocs/WORK/iframe.html' (length=30) 1 => string '/xampp/htdocs/WORK/index.html' (length=29) 2 => string '/xampp/htdocs/WORK/js' (length=21) 3 => string '/xampp/htdocs/WORK/js/btwn.js' (length=29) 4 => string '/xampp/htdocs/WORK/js/qunit' (length=27) 5 => string '/xampp/htdocs/WORK/js/qunit/qunit.css' (length=37) 6 => string '/xampp/htdocs/WORK/js/qunit/qunit.js' (length=36) 7 => string '/xampp/htdocs/WORK/js/unit-test.js' (length=34) 8 => string '/xampp/htdocs/WORK/xxxxx.js' (length=30) 9 => string '/xampp/htdocs/WORK/plane.png' (length=28) 10 => string '/xampp/htdocs/WORK/qunit.html' (length=29) 11 => string '/xampp/htdocs/WORK/styles.less' (length=30)
