1、遍历文件夹
scandir
2、原生的迭代器Iterrate
$scan_dir = "txtDir";
??//下面会遍历txtDir 下面所有字文件夹中的文件哦 ???$dir_iterator = new RecursiveDirectoryIterator($scan_dir); ???$iterator = new RecursiveIteratorIterator($dir_iterator, RecursiveIteratorIterator::SELF_FIRST);//$iterator 变量中会存储所有文件
遍历处理文件: foreach ($iterator as $file) { ???????if ($file->isFile()) { ???????????$s = $file->getPathname(); ???????????$file_name = $file->getFilename(); ???????????if($file_name == ‘a.txt‘){ ???????????????continue; ???????????}}就是这么简单
