PHPNG (next generation)

This page gives short information about development state of a new PHP branch based on refactored Zend Engine.

The phpng branch has been merged into master and has been used as the base for PHP 7.0

Some technical implementation details are available at phpng-int. Information for extension maintainers at phpng-upgrading.

PHP 7.0.0-dev (cli) (built: Apr 28 2014 11:13:04)

Copyright (c) 1997-2014 The PHP Group

You may run synthetic benchmarks

$ sapi/cli/php Zend/bench.php

$ sapi/cli/php Zend/micro_bench.php

You may measure the performance of some web applications

$ sapi/cgi/php-cgi -T 1000 /var/www/html/wordpress/index.php > /dev/null''

You may do the same with callgrind profiler

$ valgrind --tool=callgrind --dump-instr=yes --separate-recs=1 sapi/cgi/php-cgi -T 100 /var/www/html/wordpress/index.php > /dev/null

Finally, you may run PHP as FastCGI server using CGI SAPI or FPM (it requires additional configuration)

$ PHP_FCGI_CHILDREN=4 PHP_FCGI_MAX_REQUESTS=0 sapi/cgi/php-cgi -b /tmp/fcgi-php

I would recommend build PHP from master and phpng branches and compare their performance
