What is the best PHP code encryptor?
The original question was edited and changed in its sense!!! I am looking for a source encrypting software and I want to know your opinion!!! I am not looking for a obfuscator, not a YUI-like-compressor!
The best one is the one that you can use, is secure, and does what you need.
Without more information, I can't give any more advice. Are you looking for something to store code securely? Maybe you should look at something like TrueCrypt for that. If you're trying to encrypt/decrypt data via php, there's libraries for that. Without more information on what you're trying to do, you're not going to get a lot of answers.
There is a product called PHP Encoder by ionCube which is enterprise grade compression and obfuscater.
PHP Encoder is a PHP extension to create and run compiled bytecodes for accelerated runtime performance and maximum security.
It will shrink the file size, and speed up runtime because the code is already partially compiled.
check out bcompiler, it's available at pecl.php.net and is free
