How to show search related data from Google using PHP?

Anyone has any idea how do I extract some search related data, like which gender is searching a specific phrase more, which age group is searching that phrase etc, from google and show it using PHP?

For example, if you type a phrase "football", it will tell you that 70% of male and 25% of female are searching that on google. That's not an exact example but yeah somewhere along that line.

Thanks in advance.

Download it using cURL and custom parse the data into variables?

You will have to create a little programme using CURL & Preg_Match.
CURL will return content of the given URL.
preg_match will return exact match from that returned content according to your preg_match pattern.
