Answer 1

Answer:

To send a % sign in a url, instead send %25.

In your case, in order for php to see a percent sign, you must pass the character string %25B6011000995504101^SB to the server.

Why:

In URLs, the percent sign has special meaning. Is used to encode special characters. For example, & is the separator between parameters, so if you want your parameter to actually contain an &, you instead write %26. Because the percent sign is used to encode special characters, it is also a special character, and so if you want to actually send a percent sign, it must also be encoded. The encoding for a percent sign is %25.
