Introduction to the use of PHP directory traversal and deletion functions _php tutorial

It's all right. Write the function that the directory wants to close

including traversing files under this folder, directory subdirectories read the current file under directories and files delete the directory subdirectories under the current folder and files above three functionsChinese files are not currently supported in Chinese
Copy CodeThe code is as follows:
Header ("Content-type:text/html;charset=utf-8");
/**
* Read the files and directories in the current directory
*
* @param string $path path
* @return array of all files that meet the criteria
*/
function Tlist ($path) {
$path = Iconv (' utf-8 ', ' GBK ', $path);
if (!is_dir ($path)) {
throw new Exception ($path. " Not a directory ");
}
$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);
The echo "Directory is:". Implode ("
", $arr [' dir '])."
";
echo "files are:". Implode ("
", $arr [' file ']);
}
/**
* Traverse files and directories in the current directory and subfolders in the directory
*
* @param string $path path
* @return array of all files that meet the criteria
*/

if (!is_dir (Iconv ("Utf-8", "GBK", $path))) {
throw new Exception ("folder". $path. " Does not exist or is not a file ");
}
$arr = Array ();
$HD = Opendir (Iconv ("Utf-8", "GBK", $path));

}else if (Is_file ($newpath)) {
$arr [] = Iconv (' GBK ', ' utf-8 ', $file);
}
}
Closedir ($HD);
return $arr;
}
/**
