LinkedIn API Access token

Getting access token via php, there is a trick that LinkedIn even not mentioned

---

As one of my final projects is related with LinkedIn, we need to get data via API. So I tried the instruction from LindedIn Developer. However, the php code it provided could not work. After a bit research, a solution found.

Find your folder "/Apache/bin/php.ini"
uncommenting ;extension=php openssl.dll
add allow url_include = On in case of not working

end. 2014-03-26
