Ok so there are a couple of things here you should know.
1. Apache uses a file called \wamp\bin\php\php{version}\phpForApache.ini to get its php inin file setting from.
This is the file that will be edited when you use the
wampmanager -> PHP -> php.ini
MENU link to edit the php.ini file. THATS WHY ITS THERE!
2. There is a better way to UP the phpMyAdmin allocations and ONLY EFFECT phpMyAdmin and not the whole system
Edit \wamp\alias\phpmyadmin.cong
It should look like this
Alias /phpmyadmin "d:/wamp/apps/phpmyadmin4.3.8/"
# to give access to phpmyadmin from outside
# replace the lines
#
# Require local
#
# by
#
# Require all granted
#
<Directory "d:/wamp/apps/phpmyadmin4.3.8/">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
<IfDefine APACHE24>
Require local
</IfDefine>
<IfDefine !APACHE24>
Order Deny,Allow
Deny from all
Allow from localhost ::1 127.0.0.1
</IfDefine>
php_admin_value upload_max_filesize 128M
php_admin_value post_max_size 128M
php_admin_value max_execution_time 360
php_admin_value max_input_time 360
</Directory>
NOW change the relevant parameter there at the bottom of the config file and the changes will only apply to the system when phpMyAdmin is running. So you want have to wait a year when you code a unterminated while loop by accident. I know I am sure you would never do that, me neither, except I do it all the time!!!
Also a better way of adding HUGH databases to MySQL would be to use the "MySQL Console" accessed AGAIN from the wampmanager menu system.
wampmanager -> MySQL -> MySQL Console
If you have not set a password on the root account, just hit enter on the password challenge.
Then at the "mysql>" prompt enter
source C:/path/to/backup.sql
