Transforms a value into a valid JSON string.
{$user|json_encode}Depending on the value of $user this would return a string in JSON-format, e.g. {"username":"my_username","email":"my_username@smarty.net"}.
| Parameter | Type | Required | Description |
|---|---|---|---|
| 1 | int | No | bitmask of flags, directly passed to PHP's json_encode |
| 2 | string | No | input encoding; defaults to \Smarty\Smarty::$_CHARSET which defaults to UTF-8 |
By passing 16 as the second parameter, you can force json_encode to always format the JSON-string as an object.
Without it, an array $myArray = ["a","b"] would be formatted as a javascript array:
{$myArray|json_encode} # renders: ["a","b"]
{$myArray|json_encode:16} # renders: {"0":"a","1":"b"}
