Encrypt php lines
there are some lines of php code
like a copyright
that i want to encrypt
so people can't search for it and then remove it

how can i encrypt the code so it just looks like numbers and letters and not in readable format?

thanks Smilie

You can't really encrypt it and still get it run automatically. At best you can obscure it -- a temporary distraction easily bypassed, because your program by definition contains step-by-step instructions for decoding the encoded program.

Could you give an example of what you're trying to do?

There is a commercial PHP extension on the market that runs encrypted PHP code. The purpose of the engine is to decrypt PHP source code which has been encrypted to stop code modifications and copyright violations. There is an extension for this forum that uses this type of PHP source code extension, but we removed it a number of years ago.

That is not true. There is a PHP extension that encrypts source code and the decrypts it and runs the code, on the fly. The purpose of that package / extension is to encrypt PHP source code to prevent copyright violations and unauthorized code modifications.

EDIT: Check out this solution from ionCube.

ionCube PHP Encoder

The ionCube PHP Encoder makes it easy to protect your PHP 4 & 5 source code from easy observation, theft and change. Plus, with PHP licensing features built into the Pro and Cerberus editions, licensing PHP scripts to control where your code runs is easy too, and you can even give your files a time expiry! Optional encryption of non-PHP code is also supported if required.

Available in three editions, Basic (entry level), Pro and Cerberus, all ionCube PHP Encoder editions offer bytecode PHP encoding plus optional encryption of non-PHP files. Pro and Cerberus also include optional PHP licensing features for time expiry and restricting where code can be used, allowing licensing models to be effectively and easily implemented.

The PHP Encoder is available for Windows, Linux, FreeBSD and Intel OS X. All versions offer command line access for encoding, and also for creating license files using Pro or Cerberus. This feature is ideal if you wish to automate processing. The Windows Encoder also includes an easy to use GUI, and the Windows Pro and Cerberus editions include a Linux based license generator for PHP scripts too, allowing scripts to be protected using Windows and creating license files from a Linux based web server.

ionCube Encoded files run on a wide range of operating systems such as Linux, Windows, FreeBSD and others.

thanks for the responses
i dont really understand how that works

is it a program
where you can put in the php code you want to encode
and it will output the encrypted code you can use into the php file instead?

are there any websites that do this?

and once the php code is encrypted, people can still run the code anywhere? like the code will be distributed to users and i dont want them to remove the copyright when they install it on their own hosting

thanks!

I was more wondering why the need for this thing. This will not prevent anyone from using your code, only from seeing what it does...

No that is also not correct; it is easy to put a license key in the PHP code (for the person who licensed it) and an encrypted key in a file can compare the two; and this technique is routinely used to insure only licensed code is running. Some systems also use crypto hash functions for IP address or other local tokens and add that token to the source code before encrypted and providing the code to the licensee so it only runs on a certain host, IP address, etc.
