<li><strong>PHP:</strong> You are running a supported version of PHP. <em>No problems here.</em></li>
<?phpif($xml_ok):?>
<li><strong>XML:</strong> You have XMLReader support or a version of XML support that isn't broken installed. <em>No problems here.</em></li>
<?phpif($pcre_ok):?>
<li><strong>PCRE:</strong> You have PCRE support installed. <em>No problems here.</em></li>

<li><strong>cURL:</strong> You have <code>cURL</code> support installed. <em>No problems here.</em></li>
<?phpelse:?>
<li><strong>cURL:</strong> The <code>cURL</code> extension is not available. SimplePie will use <code>fsockopen()</code> instead.</li>

<?phpelse:?>
<li><strong>Zlib:</strong> The <code>Zlib</code> extension is not available. SimplePie will ignore any GZIP-encoding, and instead handle feeds as uncompressed text.</li>

<li><strong>mbstring and iconv:</strong> You have both <code>mbstring</code> and <code>iconv</code> installed! This will allow SimplePie to handle the greatest number of languages.

<?phpelseif($mbstring_ok):?>
<li><strong>mbstring:</strong><code>mbstring</code> is installed, but <code>iconv</code> is not. Check the <ahref="http://simplepie.org/wiki/faq/supported_character_encodings">Supported Character Encodings</a> chart to see what's supported on your webhost.</li>

<?phpelse:?>
<li><strong>mbstring and iconv:</strong><em>You do not have either of the extensions installed.</em> This will significantly impair your ability to read non-English feeds, as well as even some English ones.

<?phpelse:?>
<li><strong>PCRE:</strong> Your PHP installation doesn't support Perl-Compatible Regular Expressions. <em>SimplePie is a no-go at the moment.</em></li>

<p>You can download the latest version of SimplePie from <ahref="http://simplepie.org/downloads/">SimplePie.org</a> and install it by <ahref="http://simplepie.org/wiki/setup/start">following the instructions</a>. You can find example uses with <ahref="http://simplepie.org/ideas/">SimplePie Ideas</a>.</p>
<p>Take the time to read <ahref="http://simplepie.org/wiki/setup/start">Requirements and Getting Started</a> to make sure you're prepared to use SimplePie. No seriously, read them.</p>
<pclass="footnote"><em><strong>Note</strong></em>: Passing this test does not guarantee that SimplePie will run on your webhost — it only ensures that the basic requirements have been addressed.</p>

<h3>Bottom Line: Yes, you can!</h3>
<p><em>For most feeds, it'll run with no problems.</em> There are <ahref="http://simplepie.org/wiki/faq/supported_character_encodings">certain languages</a> that you might have a hard time with though.</p>

<h3>Bottom Line: We're sorry…</h3>
<p><em>Your webhost does not support the minimum requirements for SimplePie.</em> It may be a good idea to contact your webhost, and ask them to install a more recent version of PHP as well as the <code>xmlreader</code>, <code>xml</code>, <code>mbstring</code>, <code>iconv</code>, <code>curl</code>, and <code>zlib</code> extensions.</p>
