Full-Text RSS 3.8: Compatibility Test

Test Should Be What You Have
PHP 5.4 or higher 7.4.33
XML Enabled Enabled, and sane
PCRE Enabled Enabled
Zlib Enabled Enabled
mbstring Enabled Enabled
iconv Enabled Enabled
Data filtering Enabled Enabled
Tidy Enabled Disabled
cURL Enabled Enabled
Parallel URL fetching Enabled Enabled
allow_url_fopen Enabled Enabled
DOM / XML extension Enabled Enabled

What does this mean?

  1. PHP: You are running a supported version of PHP. No problems here.
  2. XML: You have XMLReader support or a version of XML support that isn't broken installed. No problems here.
  3. PCRE: You have PCRE support installed. No problems here.
  4. allow_url_fopen: You have allow_url_fopen enabled. No problems here.
  5. Data filtering: You have the PHP filter extension enabled. No problems here.
  6. Zlib: You have Zlib enabled. This allows SimplePie to support GZIP-encoded feeds. No problems here.
  7. mbstring and iconv: You have both mbstring and iconv installed! This will allow Full-Text RSS 3.8 to handle the greatest number of languages. No problems here.
  8. Tidy: The Tidy extension is not available. Full-Text RSS 3.8 should still work with most feeds/articles, but you may experience problems with some. For problem feeds we recommend you use the HTML5 parser.
  9. cURL: You have cURL support installed. No problems here.
  10. Parallel URL fetching: You have PHP's HTTP extension or curl_multi installed. No problems here.

Bottom Line: Yes, you can!

Your webhost has its act together!

You can download the latest version of Full-Text RSS 3.8 from FiveFilters.org.

Note: Passing this test does not guarantee that Full-Text RSS 3.8 will run on your webhost — it only ensures that the basic requirements have been addressed. If you experience any problems, please let us know.

Further info

IDN support

When treating an internationalized domain name (IDN) Full-Text RSS will try to make use of PHP's idn_to_ascii function to convert the domain to ASCII. If this function does not exist, you might have trouble retrieving article content from internationalized domains.

idn_to_ascii is available on this server.

HTTP module

Full-Text RSS can make use of PHP's HTTP extension or curl_multi to make parallel HTTP requests when processing feeds. If neither are available, it will make sequential requests using file_get_contents.

curl_multi will be used on this server.

Alternative PHP Cache (APC/APCu)

Full-Text RSS can make use of APC's memory cache to store site config files (when requested for the first time). This is not required, but if available it may improve performance slightly by reducing disk access.

APC is not available on this server.

HTML parser

Full-Text RSS 3.8 uses the fast libxml parser (the default PHP parser) but it will automatically make use of Gumbo (a fast HTML5 parser) if the Gumbo PHP extension is installed. Alternatively, HTML5-PHP (an HTML5 parser written in PHP) can be used by passing &parser=html5 as a parameter. The latter might produce better results than libxml for some sites, but is a little slower.

libxml will be used by default, unless HTML5 parsing is requested.

Automatic site config updates

Full-Text RSS can be configured to update its site config files (which determine how content should be extracted for certain sites) by downloading the latest set from our GitHub repository. This functionaility is not required, and can be done manually. To configure this to occur automatically, you will need zip support enabled in PHP - we make use of the ZipArchive class.

ZipArchive is available on this server.

This compatibility test has been borrowed (and slightly adapted) from the one supplied by SimplePie.org. We have kept most of their checks intact as we use SimplePie in our application.
