how to capture adwords keyword?

[spires]

Hi everyone,

 

I understand this may seem abit strange talking about adwords on a PHP site,

However, does anyone know of a PHP code that will capture the keyword typed

in from a user in google?

 

Example:

1 - I go to google,

2 - I type in 'car companies'

3 - The google ads appear on the left hand side

4 - I click on one of the ads

5 - The page i goto will GET the 'car companies' keyword

6 - text will say, "welcome, here are your 'car companies'"

 

I have seen this been done, but i dont know how it is posiable.

Can someone shed some light on iit for me please?

 

Thanks for all of your help.
