列出具有PHP递归功能的目录中的所有文件和文件夹 [英] List all the files and folders in a Directory with PHP recursive function

问题描述

我正在尝试浏览目录中的所有文件，如果有目录，则浏览其所有文件，依此类推，直到没有更多目录可访问.每个处理的项目都将添加到下面的函数中的结果数组中.尽管我不确定我能做什么/我做错了什么，但是它不起作用，但是当处理下面的代码时，浏览器的运行速度非常慢，不胜感激，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

获取目录中的所有文件和文件夹，当您拥有.或..时不要调用函数.

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)
