这是什么编码?

What kind of encoding is this: %26%23963;%26%23954; and how can I encode letters from normal utf8 to this with php?

Thanks for your help! phpheini

Looks like URL Encoding to me.

Off hand it looks like url encoded. On this site http://meyerweb.com/eric/tools/dencoder/ it comes out as σκ

σκ

It's URL-encoded:

echo urldecode('%26%23963;%26%23954'); // σκ

which would appear to be two unicode character entities:

963 - small greek sigma
954 - small greek kappa

First off, this isn't encryption... unless of course you consider ROT-13 encryption.

Looks to me that you are percent-encoding the decimal value of the UTF-8 characters.
