SimplePie Compatibility Test

+ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
TestShould BeWhat You Have
PHP¹4.3.0 or higher
XMLEnabled
PCRE²Enabled
cURLEnabled
ZlibEnabled
mbstringEnabled
iconvEnabled
+
+ +
+

What does this mean?

+
    + +
  1. You have everything you need to run SimplePie properly! Congratulations!
    2. + + +
  2. PHP: You are running a supported version of PHP. No problems here.
    3. + +
  3. XML: You have XML support installed. No problems here.
    4. + +
  4. PCRE: You have PCRE support installed. No problems here.
    5. + +
  5. cURL: You have cURL support installed. No problems here.
    6. + +
  6. cURL: The cURL extension is not available. SimplePie will use fsockopen() instead.
    7. + + + +
  7. Zlib: You have Zlib enabled. This allows SimplePie to support GZIP-encoded feeds. No problems here.
    8. + +
  8. Zlib: The Zlib extension is not available. SimplePie will ignore any GZIP-encoding, and instead handle feeds as uncompressed text.
    9. + + + +
  9. mbstring and iconv: You have both mbstring and iconv installed! This will allow SimplePie to handle the greatest number of languages. Check the Supported Character Encodings chart to see what's supported on your webhost.
    10. + +
  10. mbstring: mbstring is installed, but iconv is not. Check the Supported Character Encodings chart to see what's supported on your webhost.
    11. + +
  11. iconv: iconv is installed, but mbstring is not. Check the Supported Character Encodings chart to see what's supported on your webhost.
    12. + +
  12. mbstring and iconv: You do not have either of the extensions installed. This will significantly impair your ability to read non-English feeds, as well as even some English ones. Check the Supported Character Encodings chart to see what's supported on your webhost.
    13. + + +
  13. PCRE: Your PHP installation doesn't support Perl-Compatible Regular Expressions. SimplePie is a no-go at the moment.
    14. + + +
  14. XML: Your PHP installation doesn't support XML parsing. SimplePie is a no-go at the moment.
    15. + + +
  15. PHP: You are running an unsupported version of PHP. SimplePie is a no-go at the moment.
    16. + + +
+
+ +
+ +

Bottom Line: Yes, you can!

+

Your webhost has its act together!

+

Note: Passing this test does not guarantee that SimplePie will run on your webhost — it only ensures that the basic requirements have been addressed.

+ +

Bottom Line: Yes, you can!

+

For most feeds, it'll run with no problems. There are certain languages that you might have a hard time with though.

+

Note: Passing this test does not guarantee that SimplePie will run on your webhost — it only ensures that the basic requirements have been addressed.

+ +

Bottom Line: We're sorry…

+

Your webhost does not support the minimum requirements for SimplePie. 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 xml, mbstring, iconv, curl, and zlib extensions.

+ +
+ +
+

¹ — SimplePie 2 will not support PHP 4.x. The core PHP team has discontinued PHP 4.x patches and support. Read the announcement.

+

² — Some recent versions of the PCRE (PERL-Compatible Regular Expression) engine compiled into PHP have been buggy, and are the source of PHP segmentation faults (e.g. crashes) which cause random things like blank, white screens. Check the Support Forums for the latest information on patches and ongoing fixes.

+Images
+--------------------------
+Currently, images are stripped from the feeds as they are likely larger

+images, edit the widget view and add the img tag to the $allow_tags array.

What does this mean?

-
    - -
  1. You have everything you need to run SimplePie properly! Congratulations!
    2. - - -
  2. PHP: You are running a supported version of PHP. No problems here.
    3. - -
  3. XML: You have XML support installed. No problems here.
    4. - -
  4. PCRE: You have PCRE support installed. No problems here.
    5. - -
  5. cURL: You have cURL support installed. No problems here.
    6. - -
  6. cURL: The cURL extension is not available. SimplePie will use fsockopen() instead.
    7. - - - -
  7. Zlib: You have Zlib enabled. This allows SimplePie to support GZIP-encoded feeds. No problems here.
    8. - -
  8. Zlib: The Zlib extension is not available. SimplePie will ignore any GZIP-encoding, and instead handle feeds as uncompressed text.
    9. - - - -
  9. mbstring and iconv: You have both mbstring and iconv installed! This will allow SimplePie to handle the greatest number of languages. Check the Supported Character Encodings chart to see what's supported on your webhost.
    10. - -
  10. mbstring: mbstring is installed, but iconv is not. Check the Supported Character Encodings chart to see what's supported on your webhost.
    11. - -
  11. iconv: iconv is installed, but mbstring is not. Check the Supported Character Encodings chart to see what's supported on your webhost.
    12. - -
  12. mbstring and iconv: You do not have either of the extensions installed. This will significantly impair your ability to read non-English feeds, as well as even some English ones. Check the Supported Character Encodings chart to see what's supported on your webhost.
    13. - - -
  13. PCRE: Your PHP installation doesn't support Perl-Compatible Regular Expressions. SimplePie is a no-go at the moment.
    14. - - -
  14. XML: Your PHP installation doesn't support XML parsing. SimplePie is a no-go at the moment.
    15. - - -
  15. PHP: You are running an unsupported version of PHP. SimplePie is a no-go at the moment.
    16. - - -
-
- -
- -

Bottom Line: Yes, you can!

-

Your webhost has its act together!

-

Note: Passing this test does not guarantee that SimplePie will run on your webhost — it only ensures that the basic requirements have been addressed.

- -

Bottom Line: Yes, you can!

-

For most feeds, it'll run with no problems. There are certain languages that you might have a hard time with though.

-

Note: Passing this test does not guarantee that SimplePie will run on your webhost — it only ensures that the basic requirements have been addressed.

- -

Bottom Line: We're sorry…

-

Your webhost does not support the minimum requirements for SimplePie. 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 xml, mbstring, iconv, curl, and zlib extensions.

- -
- -
-

¹ — SimplePie 2 will not support PHP 4.x. The core PHP team has discontinued PHP 4.x patches and support. Read the announcement.

-

² — Some recent versions of the PCRE (PERL-Compatible Regular Expression) engine compiled into PHP have been buggy, and are the source of PHP segmentation faults (e.g. crashes) which cause random things like blank, white screens. Check the Support Forums for the latest information on patches and ongoing fixes.
