Windows Live SkyDrive<\/a> is one of the best online storage\/file hosting solutions available online. It provides you with 25 GBs of free storage associated with your Windows Live ID, and allows you to upload as many files as you want to it. However, Windows Live SkyDrive’s direct links are not stable for more than a day, unlike Google Docs where the direct link is stable and permanent. Here is a PHP function that can be used to obtain the direct link of a SkyDrive file using the public URL of the file.<\/p>\n

To use this function, feed it the public URL and it will return the direct link of the file:<\/p>\n
\r\n$direct = get_skydrive_direct_link("http:\/\/cid-abcdef1234567890.office.live.com\/self.aspx\/FolderName\/FileName.exe");\r\n\/\/ Returns something like http:\/\/public.bay.livefilestore.com\/y1pZwjyu-qfXUWjM-si2IeNs-juO0PjZE-Sk5EVvZxgeenjCxxv9vHiUy8q1RGafKnbaGSC2alqAoIbDvAYegznaZ\/FileName.exe\r\n$not_direct = get_skydrive_direct_link("http:\/\/not.skydrive.example.com\/not\/a\/skydrive\/FileName.exe");\r\n\/\/ Returns FALSE (if it is not a SkyDrive upload)\r\n<\/pre>\n
You can use this script as part of an independent web service or as part of your existing PHP application under the BSD license. There is a link generator on this website<\/a> available that you can use to try it out or use with your application without needing the script to be installed.<\/p>","protected":false},"excerpt":{"rendered":"
