That would have been a useful bit of information to post earlier - since you
asked why your changes to php.ini aren't being picked up, it gives the
impression you control the server in the first place...

It shouldn't do. PHP configuration, at least for the Apache module version
(another assumption - running as a module is the most common configuration) is
only read when Apache starts. Even if you could change php.ini at runtime,
which if you're just a user you can't, then it wouldn't make any difference
because PHP doesn't even read it until next startup.
Even that assumption might be inaccurate; you could be running PHP as CGI,
which is slower, but there's then the opportunity to point it at your own
php.ini file through $PHPRC or a command-line switch in the #! line at the top
of the script.

I'm trying to help but you've not given enough information, and the
situation's changed now you've said you're a user on somebody else's server,
rather than setting up your own.
Take a step back - you've been asking how to change php.ini - this is almost
certainly the wrong approach. Your ISP is not going to change something
server-wide just for your benefit, it'll break other people's scripts.
You mentioned in the original post that what you were actually trying to do is
turn off magic_quotes_gpc.
There are several places to alter PHP configuration settings:
(1) Server-wide in php.ini. Only read at startup. Only the administrator can
change it.
(2) At runtime, with ini_set(). Only works for a subset of options.
magic_quotes_gpc is not one of them. See the manual for the list.
(3) In an Apache .htaccess file. Depends on your configuration. You can change
more settings here than you can with ini_set(), but not all of them. You _can_
change magic_quotes_gpc.
And of course, read the manual: http://www.php.net/manual/en/configuration.php
Each of these options is explained there.
