About
PHP Unserializer is an AI-built single-page app in the converters category (php to json). It opens in your browser, so there is nothing to install. You provide PHP serialized data and get JSON. It needs no account. It is a plain tool: no AI model is involved. The source code is public on GitHub (simonw/tools).
