PHP Script To Get File Contents On Google Drive

I need a PHP script to use the Google Drive API to loop through the folders in a given folder and with the files inside (which will be all Sheets) return the document ID and the Sheet content, ideally as JSON. The folder structure looks like this: 1 / Sheet1 Sheet2 ... 2 / Sheet1 Sheet2 ... ... and I would want something like this returned: { 1: { 1: {awsefflsfiefjfofeofjfeoeffhofeofefepsof:[sheet content as json] 2: {awsefflsfiefjfofeofjfeoeffhofeofefepsof:[sheet content as json] ... } 2: { 1: {awsefflsfiefjfofeofjfeoeffhofeofefepsof:[sheet content as json] 2: {awsefflsfiefjfofeofjfeoeffhofeofefepsof:[sheet content as json] ... } .... }
