how to control hook calling order

Hi there, I'm creating a PHP extension of my own, and I'd like my extension's module_startup_function (i.e., PHP_MINIT_FUNC) to be the last one called among all the extensions' MINIT funcs. I'd also like my extension's request_startup_function (PHP_RINIT_FUNC) to be the first one called among all extension's RINIT funcs. Is there any way that allows me to control the calling order of the module_startup/shutdown functions and request_startup/shutdown functions of my own extension relative to other extensions? I'm using PHP-4.1.0 on Linux. Thanks a lot for your help. --Charmaine Tian
