PHP deletes the current directory and all files in it File

Use PHP to traverse all directories and files in a directory, and delete all subdirectories and files in the directory and its directories. This code is implemented recursively.

Functions used:

scandir($path) traverses all files in a directory and returns an array.

unlink($filename) Delete the file.

rmdir($path) only deletes empty folders.

PHP code:

/**
 * 删除当前目录及其目录下的所有目录和文件
 * @param string $path 待删除的目录
 * @note  $path路径结尾不要有斜杠/(例如:正确[$path=&#39;./linuxidc/image&#39;],错误[$path=&#39;./linuxidc/image/&#39;])
 */
function deleteDir($path) {
    if (is_dir($path)) {
        //扫描一个目录内的所有目录和文件并返回数组
        $dirs = scandir($path);
        foreach ($dirs as $dir) {
            //排除目录中的当前目录(.)和上一级目录(..)
            if ($dir != &#39;.&#39; && $dir != &#39;..&#39;) {
                //如果是目录则递归子目录，继续操作
                $sonDir = $path.&#39;/&#39;.$dir;
                if (is_dir($sonDir)) {
                    //递归删除
                    deleteDir($sonDir);
                    //目录内的子目录和文件删除后删除空目录
                    @rmdir($sonDir);
                } else {
                    //如果是文件直接删除
                    @unlink($sonDir);
                }
            }
