}


$scraped_page = curl("http://champion.gg/champion/Riven");
$scraped_data = scrape_between($scraped_page, '],"experienceRate":[', '],"gameLength":[');

echo $scraped_data;

It returns

46.34,48.94,50.84,53.51,55.29

But I cant seem to find out how to isolate the 48.94 (second) and 55.29 (last) values.

Any help would be highly appreciated
