This explaination does not apply to all directives. I just
exmplain about "register_globals" a bit.
If user set "register_globals" to "On" in script, it does not
initialize GET/POST, IIRC. However, changing register_globals
value during script execution is *not* meaningless.
For example, if register_globals set to on *before*
session start, session variable may be initilized as global vars.
To understand why there are many entries have PHP_INI_ALL
requires read&understand source fully....
I guess some of them can be safely set to
PHP_INI_SYSTEM|PHP_INI_PERDIR, though.
