JSON to PHP array, PHP array to JSON, PHP serialize, and PHP unserialize. All four operations are available with instant swap between input and output.
PHP serialize creates a PHP-specific string format that preserves types (objects, arrays). json_encode creates JSON format for cross-language compatibility.
Yes. Deeply nested arrays and associative arrays are handled correctly. The tool preserves the complete structure during conversion.
For JSON conversion, PHP objects are converted to JSON objects. For serialization, object notation (O:4:"name":...) is preserved in the serialized string.
No. All conversions happen locally in your browser. No PHP data is sent to any server.
