PHP scalar types map directly into JSON with no transformation. Would love it if someone could help me out. I cant find anything on the official PHP site and have been looking on Google for ages. But in our case, we’ll use an Array as an input value, and then this function will convert it into a JSON representation of the provided value.

Although JSON resembles an object or an array, JSON is a string.

Keys are always considered strings in the JSON format, while the values can be something like an object, array, string, number, and so on. The first one is known as a collection of value/key pairs. You can either fix the JSON at the source so that it returns a valid JSON structure, or you can manually add quotes around the keys. To determine if the JSON output is genuine, PHP includes a method called jsondecode (), which was introduced in PHP 5.3. JSON stands on two primary structures: object and array.
