<h1>Download documentation</h1>

<p>
 The PHP manual is available in a selection of languages and
 formats. Pick a language and format from the table below to start
 downloading.
</p>

<h2>Notes to read before you download</h2>

<ul>
 <li>
  The English version should be considered the most accurate, since
  translations are based on that version. Most of the translations
  are not complete, and contain English parts. 
 </li>
 <li>
  The packaged HTML version of the manual (tar.gz) doesn't contain
  any directories, so all of the files will be dumped into your
  current working directory when you expand the archive unless the
  tool you use does otherwise.
 </li>
 <li>
  <p class="warn">
  If you are using Microsoft Internet Explorer under Windows XP SP2 or
  later and you are going to download the documentation in CHM
  format, you should "unblock" the file after downloading it, by
  right-clicking on it and selecting the properties menu item. Then click
  on the 'Unblock' button. Failing to do this may lead to errors
  in the visualization of the file, due to a Microsoft bug.
  </p>
