Hi
There is of course the \wamp\bin\php\phpx.y.z\php.ini file, used by PHP CLI ( running php scripts from the dos box)
and
\wamp\bin\apache\apachex.y.z\bin\php.ini which is used by Apache when it loads the PHP interpreter.
The \wamp\bin\apache\apachex.y.z\bin\php.ini should be a SYMLINK to the
\wamp\bin\php\phpx.y.z\bin\phpForApache.ini file.
After an initial install the \wamp\bin\php\phpx.y.z\phpForApache.ini file is copied to the \wamp\bin\apache\apachex.y.z\bin\php.ini so it is not actually a SYMLINK
But to clean up that situation it is a good idea to force WAMPServer to re-create the SYMLINKS by doing this from the wampmanager menu
wampmanager-> Apache -> Version -> and then click on the version number, probably 2.4.9 in your case.
This will make WAMPServer rebuild all the correct SYMLINKS inside the \wamp\bin\apache\apachex.y.z\bin\ folder.
The reason for this phpForApache.ini file is to facilitate switching Apache versions. Remember one of the great benefits to Web Developers is that WAMPServer allow you to have more than one Apache or MYSQL or PHP version available within WAMPServer. You can then switch between them to suit the development you are doing.
For now I would not expect you to need to do this but it may become useful later when you get more familiar with development in general and WAMPServer speifically.
