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.
Slides from a talk at ZendCon-2014 phpng-php7.pdf
How to Download, Build, Install and Test
Note: For anonymous checkout, use https://git.php.net/repository/php-src.git instead of git@git.php.net:php-src.git
mkdir ~/tmp cd ~/tmp git clone git@git.php.net:php-src.git cd php-src ./buildconf ./configure --prefix=$HOME/tmp/usr --with-config-file-path=$HOME/tmp/usr/etc --enable-mbstring --enable-zip --enable-bcmath --enable-pcntl --enable-ftp --enable-exif --enable-calendar --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-wddx --with-curl --with-mcrypt --with-iconv --with-gmp --with-pspell --with-gd --with-jpeg-dir=/usr --with-png-dir=/usr --with-zlib-dir=/usr --with-xpm-dir=/usr --with-freetype-dir=/usr --with-t1lib=/usr --enable-gd-native-ttf --enable-gd-jis-conv --with-openssl --with-mysql=/usr --with-pdo-mysql=/usr --with-gettext=/usr --with-zlib=/usr --with-bz2=/usr --with-recode=/usr --with-mysqli=/usr/bin/mysql_config make make install mkdir $HOME/tmp/usr/etc vi $HOME/tmp/usr/etc/php.ini
max_execution_time=600 memory_limit=128M error_reporting=0 display_errors=0 log_errors=0 user_ini.filename= realpath_cache_size=2M cgi.check_shebang_line=0 zend_extension=opcache.so opcache.enable_cli=1 opcache.save_comments=0 opcache.fast_shutdown=1 opcache.validate_timestamps=1 opcache.revalidate_freq=60 opcache.use_cwd=1 opcache.max_accelerated_files=100000 opcache.max_wasted_percentage=5 opcache.memory_consumption=128 opcache.consistency_checks=0
Now PHP must be installed and configured. The final check.
$ sapi/cli/php -v
PHP 7.0.0-dev (cli) (built: Apr 28 2014 11:13:04)
Copyright (c) 1997-2014 The PHP Group
Zend Engine v2.7.0-dev, Copyright (c) 1998-2014 Zend Technologies
with Zend OPcache v7.0.4-dev, Copyright (c) 1999-2014, by Zend Technologies
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
