    As this is not directly available from this page, here's the meaning of the two flags:

    ZIPARCHIVE::FL_NOCASE
    Ignore case on name lookup

    ZIPARCHIVE::FL_NODIR
    Ignore directory component

    All defined constants can be found here : http://php.net/manual/en/zip.constants.php

    If the option ZIPARCHIVE::FL_NODIR is used, the result may be ambiguous as files with the same name may occur in various directories. In this case, the first occurence in the index whoose name matches is returned.
    E.g.

    <?php
    $zip    ->addFromString('afile.txt', 'index 0');
    $zip->addFromString('double.txt', 'index 1');
    $zip->addFromString('dir/double.txt', 'index 2');
    ?>

    $zip->locateName('double.txt',ZIPARCHIVE::FL_NODIR) returns 1
