I want to get the Global search volume of a keyword programmatically by a PHP Script. By Adwords API or some other API I want to get this data.I want to know Local or Global both search volumes, if possible for a particular country. See the Thread I posted in Google Code Forum

Eric Koelda replied me back and supplied many good references as given below-

Hi Bikram,

This is possible using the TargetingIdeaService.

http://code.google.com/apis/adwords/docs/reference/latest/TargetingId...

The search volume stats are available in the GLOBAL_MONTHLY_SEARCHES,
TARGETED_MONTHLY_SEARCHES, and AVERAGE_TARGETED_MONTHLY_SEARCHES
attributes:

http://code.google.com/apis/adwords/docs/reference/latest/TargetingId...

An example using this service is included in the PHP client library:

http://code.google.com/p/google-api-adwords-php/source/browse/trunk/e...

Although, if you already know the keywords you want stats for then you
can use the IdeaType STATS instead.  If you haven't yet registered for
access to the API that can be done here:
