how to use this code???

The gist is too much old now. Many php core function from this gist are deprecated e.g. ereg_replace() . Also the API's moved at some another url's or they stopped providing free services.
We have to upgrade this gist.

Edit : Without upgrading this gist, I created new repository. I used some code from this gist.
Take a look, it is simple seo report :- SEO Report - PHP
Also added the demo (Easy to use).
