<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>
  If you are looking for PHP 5 documentation, please read
  <a href="/manual/php5.php">this explanation</a>.
 </li>
 <li>
  If you are looking for PHP 4 documentation, please read
  <a href="/manual/php4.php">this explanation</a>.
 </li>
</ul>

<p class="warn">
  If you are using Windows XP SP2 or later and you are going to download the
  documentation in CHM format, you <strong>need</strong> to &quot;unblock&quot;
  the file after downloading it by right-clicking on it in Windows Explorer and
  selecting the &quot;Properties&quot; menu item, then clicking on the
  &quot;Unblock&quot; button (on Windows Vista this is within the
  &quot;Security&quot; options).  Failure to unblock the documentation file may
  result in error messages including &quot;Navigation to the webpage was
  canceled&quot; due to Windows security restrictions.
