need opinions regarding php.ini

hi, after my host moved my account from old server (shared hosting) with php 4.4.7, mysql 4.x to new one with php 5.x and mysql 5.x. nice. they did it fast and without problems. but then I realized that every folder has it's own php.ini file?!? I "talked" to them (live chat) about this and they told me "that is how our system is setup": "... afan [20:25]: why is now different then before? xxxx [20:25]: That is not different. That has always been the case. You may not have had a php.ini in every folder, but every folder still needed its own php.ini if you wanted to change the php settings. afan [20:27]: I don't understand why I should have php.ini in every folder? it's like having admin area for each folder? xxxx [20:28]: You don't have to if you don't want to, but that is how our system is setup, so unless you don't want to change settings for all of your folders, you'll want to leave those there. afan [20:29]: ok. in case I want to change something in php.ini, how to do it on all php.ini files? xxxx [20:29]: You would change one php.ini file, then visit the link I provided, and that will show you how to copy that to all folders. ..." and I got the link with script how to change EVERY php.ini on my account (with over 10 addon domain). I still think that's not correct. I need your opinion. Thanks. -afan
