Although the open-source distribution model is widely adopted by the PHP development community and works very well in many cases; encoding and protection of PHP source code is often critical to the distribution of commercial PHP applications. NuSphere has developed Nu-Coder - a powerful PHP Encoder that enables PHP developers to protect their PHP code from tempering and unauthorized copying. Nu-Coder converts the source code of PHP Script into compiled PHP bytecodes for both accelerated runtime performance and maximum security.
