Introducing a PHP custom function that can traverse files under a folder, directory subdirectories, read directories and files under the current file, etc. There are three functions in total. Chinese is not supported at the moment. For everyone’s learning reference.
The code is as follows: <?php /** * php目录遍历与删除操作 * Edit bbs.it-home.org */ header("Content-type:text/html;charset=utf-8"); /** * 读取当前目录下的文件和目录 * * @param string $path 路径 * @return array 所有满足条件的文件 */ function tlist($path){ $path = iconv('utf-8', 'gbk', $path); if(!is_dir($path)){ throw new Exception($path."不是目录"); } $arr = array('dir'=>array(),'file'=>array()); $hd = opendir($path); while(($file = readdir($hd))!==false){ if($file=="."||$file=="..") {continue;} if(is_dir($path."/".$file)){ $arr['dir'][] = iconv('gbk','utf-8',$file); }else if(is_file($path."/".$file)){ $arr['file'][] = iconv('gbk','utf-8',$file); } } closedir($hd); echo "目录有:".implode("<br />",$arr['dir'])."<br />"; echo "文件有:".implode("<br />",$arr['file']); } /** * 遍历当前目录下的文件和目录以及子文件夹中目录 * * @param string $path 路径 * @return array 所有满足条件的文件 */ function blist($path){ if(!is_dir(iconv("utf-8","gbk",$path))){ throw new Exception("文件夹".$path."不存在或者不是文件"); } $arr = array(); $hd = opendir(iconv("utf-8","gbk",$path)); while(($file = readdir($hd))!==false){ if($file=="."||$file=="..") {continue;} $newpath=iconv('utf-8', 'gbk', $path) .'/'.$file; if(is_dir($newpath)){ $arr[] = blist($path."/".$file); }else if(is_file($newpath)){ $arr[] = iconv('gbk','utf-8',$file); } } closedir($hd); return $arr; } /** * 删除目录下的文件以及子目录 * #param string $path 路径 * #return string 删除成功返回true 失败返回false; */ function dirDel($path){ if(!is_dir($path)){ throw new Exception($path."输入的不是有效目录"); } $hand = opendir($path); while(($file = readdir($hand))!==false){ if($file=="."||$file=="..") continue; if(is_dir($path."/".$file)){ dirDel($path."/".$file); }else{ @unlink($path."/".$file); } } closedir($hand); @rmdir($path); } ?> |
