Unlink ($ filename) deletes a file.
Rmdir ($ path) only deletes empty folders

<? Php // set the folder to be deleted $ path = ". /Application/Runtime/"; // The delete folder function and the delete folder function) {// if the directory is used, continue if (is_dir ($ path) {// scan all the folders and files in a folder and return the array $ p = scandir ($ path ); foreach ($ p as $ val) {// exclude. and .. if ($ val! = "." & $ Val! = ".. ") {// Recursive Sub-directory if it is a directory, continue to operate if (is_dir ($ path. $ val) {// Delete the folder and file deldir ($ path. $ val. '/'); // Delete the empty folder @ rmdir ($ path. $ val. '/');} else {// Delete unlink ($ path. $ val) ;}}}// call the function and input the path deldir ($ path );
