Requirements
============
Web server
----------
Since phpMyAdmin's interface is based entirely in your browser, you'll need a
web server (such as Apache, nginx, :term:`IIS`) to install phpMyAdmin's files into.
PHP
---
* You need PHP 5.5.0 or newer, with ``session`` support, the Standard PHP Library
(SPL) extension, JSON support, and the ``mbstring`` extension.
* To support uploading of ZIP files, you need the PHP ``zip`` extension.
* You need GD2 support in PHP to display inline thumbnails of JPEGs
("image/jpeg: inline") with their original aspect ratio.
* When using the cookie authentication (the default), the `openssl
<http://www.php.net/openssl>`_ extension is strongly suggested.
* To support upload progress bars, see :ref:`faq2_9`.
* To support XML and Open Document Spreadsheet importing, you need the
`libxml <http://www.php.net/libxml>`_ extension.
* To support reCAPTCHA on the login page, you need the
`openssl <http://www.php.net/openssl>`_ extension.
* Performance suggestion: install the ``ctype`` extension.
