Have you ever used xpath when working on a XML file ? It's crazy.
When you work with JSON files, it's becomes a mess when you need to access data(s) on multiple level. Lots and lots of foreach / conditions...
But now, with jsonPath, parsing a JSON file haven't been so easy !
All you need to do is to import "class/jsonPath.php" to your project.
Check out example.php to have hint on how to use jsonPath ;)
Feel free to open an issue with your JSON sample !
Or you can fork the project, create a new branch and contribute :)
All JSON examples comes from json.org
