这段代码来自phpcms觉得很好,所以拿出来分享给大家,有需要的朋友可以参考一下。
<?php /** * 文件扫描 * @param $filepath 目录 * @param $subdir 是否搜索子目录 * @param $ex 搜索扩展 * @param $isdir 是否只搜索目录 * @param $md5 是否生成MD5验证码 * @param $enforcement 强制更新缓存 */ function scan_file_lists($filepath, $subdir = 1, $ex = '', $isdir = 0, $md5 = 0, $enforcement = 0) { static $file_list = array(); if ($enforcement) $file_list = array(); $flags = $isdir ? GLOB_ONLYDIR : 0; $list = glob($filepath . '*' . (!emptyempty($ex) && emptyempty($subdir) ? '.' . $ex : '') , $flags); if (!emptyempty($ex)) $ex_num = strlen($ex); foreach ($list as $k => $v) { $v1 = str_replace(PHPCMS_PATH, '', $v); if ($subdir && is_dir($v)) { scan_file_lists($v . DIRECTORY_SEPARATOR, $subdir, $ex, $isdir, $md5); continue; } if (!emptyempty($ex) && strtolower(substr($v, -$ex_num, $ex_num)) == $ex) { if ($md5) { $file_list[$v1] = md5_file($v); } else { $file_list[] = $v1; } continue; } elseif (!emptyempty($ex) && strtolower(substr($v, -$ex_num, $ex_num)) != $ex) { unset($list[$k]); continue; } } return $file_list; } ?>
