[Phpwiki-talk] fix to lib/PageList.php to remove deprecated call-time pass by reference

[Charles C. <ch...@ru...>]

In my apache error log I found another error message repeated many times
regarding call-time pass-by-reference.  The fix is

lib/PageList.php - PageList->_sortPages() - line 1114 - replace
    usort(&$this->_pages, array($this, '_pageCompare'));
with
    usort($this->_pages, array($this, '_pageCompare'));

regards,
Charles
