Php function code used to delete all files in folders and their folders

Sometimes we need to use php to delete all the files in the folder and its folder, so we can use the following code. For more information, see. Add features as required The code is as follows:
Function deldir ($ dir ){
// Delete the files in the directory first:
$ Dh = opendir ($ dir );
While ($ file = readdir ($ dh )){
If ($ file! = "." & $ File! = ".."){
$ Fullpath = $ dir. "/". $ file;
If (! Is_dir ($ fullpath )){
Unlink ($ fullpath );
} Else {
Deldir ($ fullpath );
}
}
}
Closedir ($ dh );
// Delete the current folder:
If (rmdir ($ dir )){
Return true;
} Else {
Return false;
}
}
?>

Instance: delete all the ". svn" folders under a folder (including the content to be deleted ).
The code is as follows:
Function delsvn ($ dir ){
$ Dh = opendir ($ dir );
// Find all ". svn" folders:
While ($ file = readdir ($ dh )){
If ($ file! = "." & $ File! = ".."){
$ Fullpath = $ dir. "/". $ file;
If (is_dir ($ fullpath )){
If ($ file = ". svn "){
Delsvndir ($ fullpath );
} Else {
Delsvn ($ fullpath );
}
}
}
}
Closedir ($ dh );
}
Function delsvndir ($ svndir ){
// Delete the files in the directory first:
$ Dh = opendir ($ svndir );
While ($ file = readdir ($ dh )){
If ($ file! = "." & $ File! = ".."){
$ Fullpath = $ svndir. "/". $ file;
If (is_dir ($ fullpath )){
Delsvndir ($ fullpath );
} Else {
Unlink ($ fullpath );
}
}
}
Closedir ($ dh );
// Delete the directory folder
If (rmdir ($ svndir )){
Return true;
} Else {
Return false;
}
}

$ Dir = dirname (_ FILE __);
// Echo $ dir;
Delsvn ($ dir );
?>
