How to encode URL using php like browsers do

Question

I have an URL like this

http://www.example.com/Data/image/office-dôn-sì-à.jpg

I want to copy that file to my server using copy function in php. So the first thing is to encode it to this (I think browsers do the same thing)

http://www.example.com/Data/image/office-d%C3%B4n-s%C3%AC-%C3%A0.jpg

But if I use function urlencode, full url will be encoded to

http%3A%2F%2Fwww.example.com%2FData%2Fimage%2Foffice-d%C3%B4n-s%C3%AC-%C3%A0.jpg

which is not an URL anymore and not what I want.

Any help?

The encoded ULR is copied from address bar in FF. I did change its host name due to privacy. I want to copy file using: copy('http://www.example.com/Data/image/office-d%C3%B4n-s%C3%AC-%C3%A0.jpg', 'destination.jpg'); — user342960

If you are sure that only the last piece (the filename) will contain special characters you can use Russel's solution. — vbence

So, the other answers here have largely ignored your post, it seems. Let's hope I have not done the same.

It seems to me that you only want to encode the basename? If that is true, this ad-hoc function should do the trick:

function encode_basename($url) { $url = explode('/', $url); $base = array_pop($url); return implode('/', $url) . '/' . urlencode($base); } //returns: http://www.example.com/Data/image/office-d%25C3%25B4n-s%25C3%25AC-%25C3%25A0.jpg

function encode_basename($url) { $url = explode('/', $url); $base = array_pop($url); return implode('/', $url) . '/' . rawurlencode($base); }
This answer shouldn't be marked as accepted as it doesn't solve the question. As others pointed out, you cannot use urlencode() but rawurlencode().
No difference. This basename-only solution was not an answer anyway. And in this case, urlencode and rawurlencode are the same issue.
