JSON Encode with [ ]

Question

I cant seem to get my json_encode to include brackets.. Any help?

My code is:

$th = json_encode(array("4" => "four", "8" => "eight"));
echo $th;

and the output is:

{"4":"four","8":"eight","9":"\n"}

The output I need to send to the api is:

[{"4":"four","8":"eight","9":"\n"}]

How can I get the brackets in the JSON array? Thank you!

Answer 1

Use this

$th = json_encode(array(array("4" => "four", "8" => "eight", "9" => "\n")));

Answer 2

You should do this way:

$th = json_encode(array(array("4" => "four", "8" => "eight")));
