Two ways to get files in a folder in php

Two methods for php to obtain files in a folder:

Traditional method:

When reading the contents of a folder

Use opendir readdir combined with while loop filtering to operate the current folder and parent folder

function readFolderFiles($path) { $list = []; $resource = opendir($path); while ($file = readdir($resource)) { //排除根目录 if ($file != ".." && $file != ".") { if (is_dir($path . "/" . $file)) { //子文件夹，进行递归 $list[$file] = readFolderFiles($path . "/" . $file); } else { //根目录下的文件 $list[] = $file; } } } closedir($resource); return $list ? $list : []; }

Method 2
Use the scandir function to scan the contents of the folder instead of reading in the while loop

function scandirFolder($path) { $list = []; $temp_list = scandir($path); foreach ($temp_list as $file) { //排除根目录 if ($file != ".." && $file != ".") { if (is_dir($path . "/" . $file)) { //子文件夹，进行递归 $list[$file] = scandirFolder($path . "/" . $file); } else { //根目录下的文件 $list[] = $file; } } } return $list; }
