How to hide url parameters in Php

How does Php hide the url of the get method following the url parameter? How does Php hide the first url without post? All
Http://test.com/test? Username = & pcname = & remoteIP = & dtime1 = & dtime2 = & result = & region = sh & ticket = 5219783F8B
To achieve this, you can:
Http://test.com/test /#
Thank you very much for providing detailed methods.

// Find an encryption algorithm on the Internet, suppose the method is a $ key = a ('username = & pcname = & remoteIP = & dtime1 = & dtime2 = & result = & region = sh & ticket = 5219783F8B '); http://test.com/test? Key = $ key

How to write this Rewrite rule
/Abc/dcb
Convert from rewrite? C = abc & B = dcb
/Abc/dcb? ** = Cgg .....
Convert from rewrite? C = abc & B = dcb & ** = cgg .....

echo 'http://test.com/test/'.base64_encode('username=xx&pcname=yy&remoteIP=zz&region=sh&ticket=5219783F8B');//http://test.com/test/dXNlcm5hbWU9eHgmcGNuYW1lPXl5JnJlbW90ZUlQPXp6JnJlZ2lvbj1zaCZ0aWNrZXQ9NTIxOTc4M0Y4Qg==parse_str(base64_decode('dXNlcm5hbWU9eHgmcGNuYW1lPXl5JnJlbW90ZUlQPXp6JnJlZ2lvbj1zaCZ0aWNrZXQ9NTIxOTc4M0Y4Qg=='),$arr);echo "
";print_r($arr);echo "
";/*Array(    [username] => xx    [pcname] => yy    [remoteIP] => zz    [region] => sh    [ticket] => 5219783F8B)*/

1. encrypted url parameters
2. use POST

The first and third floors are supported!
The second floor has great limitations! Generally, url rewriting can be performed for static pages.

Base64_encode and base64_decode can be decrypted. Therefore, you must add a key to encrypt and decrypt the data.
For example:
Http://blog.csdn.net/fdipzone/article/details/8178982

Anti-gentleman or anti-villain? If it is an anti-bot, we recommend that you give up directly or use https + post instead. If you are an anti-DDoS professional, refer to the encryption algorithm upstairs for encryption. However, it is easy to decrypt the data.

What do I do if I have read the expected address of the landlord without parameters and do not need post?
The first few answers should contain at least one parameter.

I feel that it is of little practical use. Even if the URL is encrypted, you can decrypt it.

Ajax is not obvious.
