Loop over JSON objects and process to custom JSON response

In PHP a variable such as $match = "[login to view URL]" is passed to a function as argument You will write function like get_positions($match){...} Loop over JSON objects in [login to view URL] Check each "serp" node "base_url" where base_url contains $match. In sample file the serp keys are number 5 and number 8. The expected output is below. Because we have 1 match in position 5. We add 1 to the output for "4-5" this is a range. And for number match 8. It goes "6-10". There will be many matches so the value of the ranges must increase if more matches are found within range. { "position_counts":{ "20080919": { "1-3": 0, "4-5": 1, // From sample match key 5 "6-10": 1, // From sample match key 8 "11-20": 0 } } }
