While PHP has been originally created Rasmus Lerdorf in 1995, main performance PHP is made now by Group PHP and serves as the actual standard for PHP as there is no formal specification. Let out according to License PHP, the Fund of the Free software believes, what is it the free software.




PHP is widely used scripting language of a general purpose to which especially satisfy for development of a network and an investment in HTML.

As well as with many scripting languages, originals PHP are usually saved as the chelovecheski-legible initial text, even on servers of a network of manufacture. Therefore these originals PHP will be collected in time of performance by engine PHP. Compilation in performance time increases time of performance of the original because he adds an additional step to performance time. Originals PHP can be collected before performance time, using compilers PHP in the same way as other programming languages, such as C.

The code optimizer improves quality from broadcasted programs, reducing its size and doing changes which can reduce time of performance and improves job. Compiler PHP nature is that, that more often there are possibilities of code optimisation, and as a code example optimizer serves Zend Optimizer PHP expansion.

Accelerators PHP can offer essential profit of job, hiding the collected form for emergency in shared memory to avoid original PHP top of parsing and compilation of the code each time at original run.
