Paste JSON to see exactly what json_decode() gives you, as PHP array code or print_r() output. Or paste a PHP array and get json_encode() output with the flags you choose.
Converted in your browser. Nothing is uploaded.
Choose json_decode (JSON → PHP) or json_encode (PHP → JSON) and paste your input. It converts as you type.
For decoding, choose arrays or stdClass objects and PHP code or print_r(). For encoding, tick the JSON_* flags you use.
Copy or download the result, or Swap to convert it back. The line at the bottom is the matching PHP code.
json_decode($json, true) returns associative arrays. Without it (or with false), JSON objects become stdClass objects, accessed as $data->name instead of $data['name'].
A PHP array becomes a JSON list only when its keys are 0, 1, 2, … in order. Any other keys (strings, gaps, a different order) give a JSON object. Use array_values() to get a list.
By default json_encode writes / as \/ and non-ASCII characters as \u00e9. Add JSON_UNESCAPED_SLASHES and JSON_UNESCAPED_UNICODE to keep them as they are.
Arrays in [] or array() syntax, strings, numbers, true, false and null, nested as deep as you like. A full statement like $data = [...]; or return [...]; works too. Variables, constants and function calls can't be evaluated in the browser.
