Example to explain how to delete a folder with php

To delete a folder in PHP, usually use recursively to delete, the following are the specific steps:

1. Open the folder and scan the subdirectory: use opendir()Open the folder and scan the files/folders using the readdir() method. While scanning, check whether each subdirectory is a folder or file and store the paths to multiple levels of subdirectories in an array.

   function deleteFolder($folderPath) {
       if (!is_dir($folderPath)) return false; // 确认路径是一个目录
       $folderIterator = new RecursiveDirectoryIterator($folderPath, RecursiveDirectoryIterator::SKIP_DOTS);
       $iterator = new RecursiveIteratorIterator($folderIterator, RecursiveIteratorIterator::CHILD_FIRST);
       foreach ($iterator as $file) {
           if ($file->isDir()){
               rmdir($file->getRealPath());
           }else{
               unlink($file->getRealPath());
           }
       }
       rmdir($folderPath);
       return true;
   }

2. Recursively delete all files and folders: In step 1, multiple levels of subdirectory paths are stored. Now, iterate over the array in reverse order, since deleting subfolders of a folder must be performed first.
3. Delete the root folder: Ultimately, just use the rmdir() function to delete the root folder.

Full code:

function deleteFolder($folderPath) {
    if (!is_dir($folderPath)) return false; // 确认路径是一个目录
    $folderIterator = new RecursiveDirectoryIterator($folderPath, RecursiveDirectoryIterator::SKIP_DOTS);
    $iterator = new RecursiveIteratorIterator($folderIterator, RecursiveIteratorIterator::CHILD_FIRST);
    foreach ($iterator as $file) {
        if ($file->isDir()){
            rmdir($file->getRealPath());
        }else{
            unlink($file->getRealPath());
        }
    }
    rmdir($folderPath);
    return true;
}

Usage example:

$folderPath = "path/to/your/folder/";
deleteFolder($folderPath);
echo "文件夹删除成功！";

Note: This code will directly delete the folder and all its contents without prompting for confirmation. Therefore, make sure you have backed up everything in this folder before using it.
