Added file_exists and is_readable test here and an array for collecting files that aren't found or aren't readable
                 $_outList[count($_outList)] = $_addFile." ->
".str_replace('t-', '', $_sep[1]);
                 $_add = $_zipper->addFile($_addFile,
str_replace('t-', '', $_sep[1]));
                 if($_add === false) // perhaps I shouldn't use === here?
At least for testing purposes, I would do
                   if($_add !== true)
                   {
                    $_addErrs[count($_addErrs)] = $_addFile;
                    continue;
                   }
                }
             $_zipper->close();
changed to $_cls = $_zipper->close(); and added test for return value of true
                     if($_cls == true)
                      {
                        $_res = "Zip archive file: ".$_name."
created\n".implode($_outList, "\n");
                      }
                  else
                     {
                      $_res = "ZipArchive returned false."
                      $_res .= "\n".implode(<files not found or not readable array>, "\n")
                     }
It's better to check the return value of ZipArchive::close().
             $_res = "Zip archive file: ".$_name."
created\n".implode($_outList, "\n");
             if(count($_addErrs) > 0)
               {
                $_res .= "\nadd errors: ".implode($_addErrs, "\n");
               }
            }
          else
            {
             require_once("php/zpArchConst.php");
             $_res = $_constER[$_ret];
            }
         }
The output back to the submitting page: Zip archive file: /dev_lab_current/lab_8/storage/new.zip created /Library/WebServer/Documents/dev_lab_current/consoleTestGrid.txt -> testGrid.txt NOTICE: the lack of $_addErrs in the output;
so, all I get is the string "ZipArchive returned false." without any listing for files that aren't found or are not readable
I am using absolute file system file paths and not docRoot relative or absolute paths
Like localhost/path-to-file/file Ah... is there another compression scheme I can use in php to create archive files... Gzip or bzip? I have looked and don't see any explicit create function for these.
The whole point is that ZipArchive->addFile is returning true and the files are NOT being added, so the zip file in not actually created
There is a user contributed note[1] on the man page stating that adding non-existing files would succeed and return TRUE; I have not been able to reproduce that, but it might be worthwhile to add a check for is_readable().
I could have the path to the file to be added constructed wrong, but I know the file exists. I will use that test.
