Storing Array in JSON
A valid JSON object always starts with { and ends with }, and an array is enclosed within [ and ]. Look at http://json.org.
If it is just an array you want to store and not store a name attribute to it. You can just store it as [1,2,3,4,5,6]. For example if you are storing it in an RDBMS, you may name the column as array and store the value as a JSON array.
In case you want to preserve the name of the attribute, or possibly want to have more attributes, you got to use this format: {"array" : [1,2,3,4,5,6]}
The accepted answer is wrong. JSON can start and end with an array. The official JSON document says
JSON is built on two structures:
- A collection of name/value pairs. In various languages, this is realized as an object, record, struct, dictionary, hash table, keyed list, or associative array.
- An ordered list of values. In most languages, this is realized as an array, vector, list, or sequence.
You can also see it through JSON validator.
In a nutshell, while you still cannot do "array" : [1,2,3,4,5,6], you can store it like [1,2,3,4,5,6].
No, that is the way the JSON is formatted
The opening/closing { } are saying this is in json (I guess kind of like <html></html>)
There is no reason you can't do
{ "array" : [1,2,3,4,5,6] }
What this is saying is that there is one field called array which contains an array of numbers
