I am stumped

Hello; I have the following code snips from isolated development project: I have been doing lots of coding similar to this and don't ever remember encountering this type of problem. I have a working version based on this elsewhere, as well. I saved this message as a draft while I looked over the working code and accept for variable name differences and differences in foreach looping construct: file or dir is tested in the looping construct and not in core gerDirListSingle code. This is supposed to scan a directory and produce an associative array where the index is the file listing and the value is either directory or file. In the loop, $_itr is set to 1 instead of 0 to try and solve the eventual output question, but doesn't do it in tests. private function getDirListSingle($_dir) { $_DR = []; if(($_DR = scandir($_dir)) === false) { self::$_readError[count(self::$_readError)] = $_dir." not scanned"; return; } for($_itr = 1; $_itr < count($_DR); $_itr++) { switch($_DR[$_itr]) { case '.': case '..': break; default: if(is_dir(self::$_homePath.'/'.$_DR[$_itr])) { self::$_dirsToRead[$_DR[$_itr]] = 'directory'; } else { self::$_dirsToRead[$_DR[$_itr]] = 'file'; } break; } } } next is code to produce a string representation of the array: ($_list['dirs'] is a copy of self::$_dirsToRead) foreach($_list['dirs'] as $_ind=>$_val) { $_outList[count($_outList)] = $_val.": ".$_ind; } $_out = implode($_outList, "\n"); The following is the result: testBed is the directory being read for this Why is testBed/test_1 included and the value is 1 instead of 'directory'. At the bottom of the list is test_1 listed as a file. Perhaps I have gone blind and can't see a mistake I should be seeing. // $_out printed out: 1: testBed/test_1 file: hello.txt file: hello_1.txt file: index.php file: test_1 Thanks for time and attention; JK
