How can you encode a PHP array into a JSON object?

  • json_encode()
  • json_serialize()
  • json_convert()
  • All of the above
To encode a PHP array into a JSON object, you can use the json_encode() function. It converts a PHP value (such as an array) into its JSON representation. The other mentioned options (json_serialize(), json_convert()) are not valid PHP functions for encoding an array into a JSON object. For further details, refer to the PHP documentation on json_encode(): http://php.net/manual/en/function.json-encode.php
