+
+ +
+

What does this mean?

+
    + + +
  1. You have everything you need to run properly! Congratulations!
    2. + + +
  2. PHP: You are running a supported version of PHP. No problems here.
    3. + +
  3. XML: You have XMLReader support or a version of XML support that isn't broken installed. No problems here.
    4. + +
  4. PCRE: You have PCRE support installed. No problems here.
    5. + + +
  5. allow_url_fopen: You have allow_url_fopen enabled. No problems here.
    6. + + +
  6. Data filtering: You have the PHP filter extension enabled. No problems here.
    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 to handle the greatest number of languages. No problems here.
    10. + +
  10. mbstring: mbstring is installed, but iconv is not.
    11. + +
  11. iconv: iconv is installed, but mbstring is not.
    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.
    13. + + + +
  13. Tidy: You have Tidy support installed. No problems here.
    14. + +
  14. Tidy: The Tidy extension is not available. should still work with most feeds, but you may experience problems with some.
    15. + + + +
  15. cURL: You have cURL support installed. No problems here.
    16. + +
  16. cURL: The cURL extension is not available. SimplePie will use fsockopen() instead.
    17. + + + +
  17. Parallel URL fetching: You have HttpRequestPool or curl_multi support installed. No problems here.
    18. + +
  18. Parallel URL fetching: HttpRequestPool or curl_multi support is not available. will use file_get_contents() instead to fetch URLs sequentially rather than in parallel.
    19. + + + +
  19. Data filtering: Your PHP configuration has the filter extension disabled. will not work here.
    20. + + + +
  20. allow_url_fopen: Your PHP configuration has allow_url_fopen disabled. will not work here.
    21. + + + +
  21. PCRE: Your PHP installation doesn't support Perl-Compatible Regular Expressions. will not work here.
    22. + + +
  22. XML: Your PHP installation doesn't support XML parsing. will not work here.
    23. + + +
  23. PHP: You are running an unsupported version of PHP. will not work here.
    24. + + +
+
+ +
+ + +
