I still think it's an issue on your end, I created this test script below, it will test if you can connect to google.com via file_get_contents and curl.
It should output the google homepage twice.
Warning: file_get_contents() [function.file-get-contents]: php_network_getaddresses: getaddrinfo failed: No such host is known. in C:\wamp\www\test.php on line 6
Warning: file_get_contents(Google) [function.file-get-contents]: failed to open stream: No error in C:\wamp\www\test.php on line 6
Could not retrieve contents. (file get contents)error retrieving contents (curl).
Pingbacks allow you to notify a weblog of your entry just by posting its permalink directly in the content of your blog entry. No special trackback link necessary.
Yeah it's the same thing, wordpress calls it a pingback, others call it a trackback.
It doesn't have to be from a blog/wordpress as many people try to *ahem* exploit tracbacks using scripts to link back to their site. Any blogs with unmoderated trackbacks can be used to gain links. It can just be a standalone php script.
Oh well I'll just have to get off my lazy ass to code one myself!![]()
Now where did I put my copy of "Dummies Guide to php".... lol
Edit: Actually if anyone has a clue what I'm talking about do you have any pointers on how to get started with a trackback script? I know a bit of php but just need to know what to look out for etc.
