JSON (JavaScript Object Notation) is a simple data-interchange format. Meaning it is an easy to use method to interchange data.

JSON Object

This method allows you to create and define a JSON Object and its elements. A JSON object is defined between braces {}. Within the braces you can define the elements of the objects well as the value of that element.

• NameOfJSONObject = { ElementName:"Value" }

If you wanted to echo the above "Value" that was given to the element called "ElementName", You can do this:

• echo NameOfJSONObject.ElementName

The result of this would be:

•  (City Name) - Value
   (City Name) - Script stopped

json_encode

json_encode() will allow you to encode a JSON object.

If you attempted to echo a JSON Object (the object itself, not an element within) it would output this:

• (City Name) - [object Object]

This is due to it being encoded in the JSON language. To be able to get valid data from the object, json_encode is needed.

• thejson = {this:"that"}
  echo json_encode(thejson)

Outputs:

•  (City Name) - {"this":"that"}
   (City Name) - Script stopped
