The INI writer has two modes for rendering with regard to sections. By default the top-level configuration is always written into section names. By calling $writer->setRenderWithoutSections(); all options are written into the global namespace of the INI file and no sections are applied.
Zend_Config_Writer_Inihas an additional option parameter nestSeparator, which defines with which character the single nodes are separated. The default is a single dot, which is accepted byZend_Config_Iniby default.
