Pingbacks don't work with allow_url_fopen=Off

[anonymousbugger]

pingback_ping() uses @fopen($pagelinkedfrom, 'r') to check if the source URI exists. This check always fails if allow_url_fopen is Off (recommended setting), that means pingbacks don't work.

Please consider replacing this fopen call with something like the code from ​http://7sheaven.pingouin.ca/forum/showthread.php?t=13

I can't use the code from the link if the link doesn't work.

Just use snoopy instead of fopen($url)

[MC_incubus]

Agreed. We're bundling Snoopy with WordPress, and using it will increase compat.

[matt]

So remote fwrites work even if remote fopen is off?

[matt]

Dreamhost, which recently disabled remote fopen, is suggesting users use curl. Curl is only used in Snoopy for SSL connections.

We may also want to upgrade snoopy.

[anonymousbugger]

I think the CURL PHP module is the way to go.

The module is available on a lot of hosts, the 'curl' binary isn't (especially in chroot environments). So if you continue to use Snoopy, it should be modified to use the module instead of the binary.

Possible fix checked in, please confirm
