There are some problems with a few PECL packages.


# 404 (Not Found) errors for version details

For example, https://pecl.php.net/rest/r/big_int/allreleases.xml says that the big_int package has version 1.0.1.
But when we fetch https://pecl.php.net/rest/r/big_int/1.0.1.xml we have a 404 response (other versions work without problems, see for example https://pecl.php.net/rest/r/big_int/1.0.0.xml and https://pecl.php.net/rest/r/big_int/1.0.2.xml ).

# 404 (Not Found) errors for packages

For example, https://pecl.php.net/rest/r/operator/allreleases.xml says that the operator package has version 0.1.
But when we fetch http://pecl.php.net/get/operator-0.1 we have a 404 response (other versions work without problems, see for example https://pecl.php.net/get/operator-0.4.1).
This error occurs for the following packages and versions:
- operator: 0.1, 0.2, 0.3
- PDO_SQLANYWHERE: 0.1.0


# Other issues:

- https://pecl.php.net/rest/r/event/1.10.2.xml has an invalid encoding, neither the browser nor the PHP DOMDocument can read it
- https://pecl.php.net/get/APC-3.0.18.tgz returns a 500 Internal Server Error response (but http://pecl.php.net/get/APC-3.0.18 works)
- these URLs return 0 bytes (those versions should exist accordingly to the allreleases.xml file of the related packages:
  - https://pecl.php.net/rest/r/zendopcache/7.0.0.xml
  - http://pecl.php.net/get/win32ps-1.0.0
  - http://pecl.php.net/get/win32ps_dll-1.0.0
