SimplePie is a very fast and easy-to-use class, written in PHP, that puts the ‘simple’ back into ‘really simple syndication’. Flexible enough to suit beginners and veterans alike, SimplePie is focused on speed, ease of use, compatibility and standards compliance.


  • PHP 5.3.0+ (5.3.6+ recommended since SimplePie 1.4.2)
    • Support for PHP 5.2 stopped in branch one-dot-three
    • Support for PHP 4 stopped in branch one-dot-two
  • libxml2 (certain 2.7.x releases are too buggy for words, and will crash)
  • One of iconv, mbstring or intl extensions
  • cURL or fsockopen()
  • PCRE support

What comes in the package?

  1. library/ - SimplePie classes for use with the autoloader
  2. autoloader.php - The SimplePie Autoloader if you want to use the separate file version.
  3. README.markdown - This document.
  4. LICENSE.txt - A copy of the BSD license.
  5. compatibility_test/ - The SimplePie compatibility test that checks your server for required settings.
  6. demo/ - A basic feed reader demo that shows off some of SimplePie’s more noticeable features.
  7. idn/ - A third-party library that SimplePie can optionally use to understand Internationalized Domain Names (IDNs).
  8. build/ - Scripts related to generating pieces of SimplePie

Since SimplePie 1.3, we’ve split the classes into separate files to make it easier to maintain and use.

If you’d like a single monolithic file, you can run php build/compile.php to generate SimplePie.compiled.php.
