In web development, we may encounter the need to empty all the files in a directory without deleting the subdirectories (and of course not deleting the deleted root directory). So what do you do with a way to delete a file without deleting the directory? Below the blogger will share with you a better solution to the problem. Look at the following function:

/* Delete files in specified directory, do not delete directory folder
/function Delfile ($dirName) {
	if (file_exists ($dirName) && $handle =opendir ($ DirName)) {while
		(false!== ($item = Readdir ($handle))) {
			if ($item!= "." && $item!= "...") {
				if (file_exists $dirName. ' /'. $item) && Is_dir ($dirName. ' /'. $item)) {
					delfile ($dirName.) /'. $item);
				} else{
					if (unlink ($dirName. ') /'. $item)) {return
		}}} Closedir ($handle);
