PHP directory traversal, deletion of the use of the function introduction _php example

It's okay, I wrote a list of functions I want to turn off.

Includes traversing files under this folder, directory subdirectories reading current files under directories and files delete directory subdirectories under current folder and files above three functions currently do not support Chinese document Chinese directory

Copy Code code as follows:

<?php
Header ("Content-type:text/html;charset=utf-8");
/**
* Read the files and directories in the current directory
*
* @param string $path path
* @return array All files that meet the criteria
*/
function Tlist ($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 has:". Implode ("<br/>", $arr [' dir ']). " <br/> ";
The echo "file has:". Implode ("<br/>", $arr [' file ']);
}
/**
* Traverse the current directory of files and directories and subfolders in the directory
*
* @param string $path path
* @return array All files that meet the criteria
*/
function Blist ($path) {
if (!is_dir (Iconv ("Utf-8", "GBK", $path))) {
throw new Exception ("folder". $path. " Does not exist or is not a document ");
}
$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;
}
/**
* Delete files and subdirectories under the directory
* #param string $path path
* #return String Deletion succeeded returning true failed to return false;
*/
function Dirdel ($path) {
if (!is_dir ($path)) {
throw new Exception ($path. " Input is not a valid directory ");
}
$hand = Opendir ($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);
}
?>
