Simple PHP Page - JSON decode and print data

Hi have a JSON response which comes from AWS API Gateway, Lambda and MongoDB.

here is the API url, feel free to test; (note just 'id' is used).

https://upuwbrkiw8.execute-api.us-east-2.amazonaws.com/test/cvemetadata?id=CVE-2001-0003

I would like help to create a php page which can read the url and extract the following info;

Data to be processed;

"publishedDate"

"cve.CVE_data_meta.ID"
"cve.affects.vendor.vendor_data.vendor_name"
"cve.description.description_data.value"
"cve.problemtype.problemtype_data.description.value"

"impact.baseMetricV2.severity"
"impact.baseMetricV2.cvssV2.confidentialityImpact"
"impact.baseMetricV2.cvssV2.integrityImpact"
"impact.baseMetricV2.cvssV2.availabilityImpact"
"impact.baseMetricV2.cvssV2.accessVector"
"impact.baseMetricV2.cvssV2.baseScore"

And a count of data "cpe23Uri" occurrences.

Additional notes;
FYI - please see attached word doc of data highlighted for the above.

I am also open to hearing if there are better ways to do this or if adjustments need to be made in AWS API Gateway or Lambda, i can provide access if necessary.

thanks
