In HTTP there's no length-limit for URI,and there's no note of file_get_contents() about this in the manual .So I think you needn't to consider about this problem.

BTW,the length of URI is limited by some browser and webserver.For example,in IE,the length should be less than 2083 and in FF it's 65,536.I tried to test this I found that only not more than 8182 is OK when I visited my apache on ubuntu because of limit of my apache.

As others have stated, it is most likely limited by the HTTP protocol.

You can view this answer for more info on that : What is the maximum length of an url?

I suppose there is a maximum length, but you'll be hard pressed to find it. If you do hit the maximum, you're doing something wrong. :)

I haven't been able to find a number for PHP specifically, but MS IIS, Apache and the Perl HTTP::Daemon seem to have limits between 4,000 and 16,384 bytes, PHP will probably be somewhere around there as well.

What you need to consider is not really how much your side can handle, but also how much the other server you're querying can handle (which is presumably what you're doing). As such, any URL longer than ~1000 characters is usually already way too long and never really encountered in the real world.
