Les performances de PHP7 dans des scénarios réels sont en effet comparables à celles de HHVM, et dépassent même HHVM dans certains scénarios. Le fonctionnement et la maintenance de HHVM sont complexes et il s'agit d'un modèle multithread. Cela signifie que si un thread provoque un crash, l'ensemble du service se bloquera et ne redémarrera pas automatiquement. De plus, il utilise JIT, ce qui signifie qu'il doit être réchauffé après le redémarrage. Sans préchauffage, les performances seront pires. De plus, le modèle multithread est difficile à déboguer, ce qui est très inadapté aux services Web qui recherchent la stabilité.

Pour les versions antérieures à Nginx et PHP7.0, merci de vous référer à cet article : Environnement Linux Installation et débogage de Nginx et installation de PHP

La version officielle de PHP7.0 a été publiée vers novembre 2015, et est actuellement la version PHP7.0.2, j'ai commencé à suivre la première version bêta de php7 en août 2015, et maintenant la version officielle est publiée.

Version Linux : CentOS 6.6 64 bits

Version Nginx : nginx1.8.0

Version php : php-7.0.2

Télécharger

# wget http://php.net/get/php-7.0.2.tar.gz/from/a/mirror

Il est recommandé de lire le fichier d'aide à l'installation INSTALL

Décompressez et installez

# tar zxvf php-7.0.2.tar.gz

# cd php-7.0.2

Vérifiez d'abord l'aide à l'installation

# ./configure --help

# ./configure --prefix=/usr/local/php

--with-curl
--with-freetype-dir
--with-gd
--with-gettext
--with-iconv-dir
--with-kerberos
--with-libdir=lib64
--with -libxml-dir
--with-mysqli
--with-openssl
--with-pcre-regex
--with-pdo-mysql
--with-pdo-sqlite
--with-pear
--with-png-dir
--with-xmlrpc
--with-xsl
--with-zlib
--enable-fpm
--enable-bcmath
--enable-libxml
--enable-inline-optimization
--enable-gd-native-ttf
--enable-mbregex
- -enable-mbstring
--enable-opcache
--enable-pcntl
--enable-shmop
--enable-soap
--enable-sockets
--enable -sysvsem
--enable-xml
--enable-zip

Si la configuration est incorrecte, vous devez installer les modules requis et installer les modules dépendants bibliothèques directement avec yum

# yum -y install libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel mysql pcre-devel

Remarque : Plusieurs configurations ne peuvent pas être configuré lors de l'installation de php7beta3. Vous devez le miam maintenant. Ce n'est plus le cas avec php-7.0.2.

# yum -y install curl-devel

# yum -y install libxslt-devel

Compiler et installer

# make && make install



Fichier de configuration

#cp php.ini-development /usr/local/php/lib/php.ini

# cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf

# cp /usr/local/php/etc/php- fpm .d/www.conf.default /usr/local/php/etc/php-fpm.d/www.conf

# cp -R ./sapi/fpm/php-fpm /etc/init .d/php-fpm

Il convient de noter que le fichier de configuration www.conf dans php7 configure le numéro de port et d'autres informations de phpfpm. Si vous modifiez le numéro de port 9000 par défaut, vous devez le changer ici. , puis modifiez la configuration nginx

Démarrer

# /etc/init.d/php-fpm

Afficher phpinfo()



Comparaison de l'analyse des performances de php7 et php5

<?php
//time /usr/local/php5/bin/php search_by_key.php
$a = array();
    for($i=0;$i<600000;$i++){
        $a[$i] = $i;
        }

    foreach($a as $i)
    {
        array_key_exists($i, $a);
    }
?>
Générer un tableau de 600 000 éléments et déterminer si la clé existe en recherchant la clé.



PHP version 5.4.44

[root@localhost www5.4.44]# heure /usr/local/php5.4.44/bin/php search_by_key.php

réel 0m0.351s
utilisateur 0m0.300s
sys 0m0.050s

PHP version 5.5.28
[root@localhost www]# time /usr/local/php /bin/php search_by_key.php
real 0m0.361s
user 0m0.304s
sys 0m0.057s

PHP version 7.0.0
[root@localhost www7]# time /usr/local/php7/bin/php search_by_key.php
real 0m0.114s
user 0m0.097s
sys 0m0.017s

Évidemment, les performances de php7 sont php5 3 fois !

Configurer opcache

Adresse du site Web officiel : http://php.net/opcache

Utilisez les paramètres recommandés suivants pour obtenir de meilleures performances :

opcache.memory_consumption=128
opcache.interned_strings_buffer=8
opcache.max_accelerated_files=4000
opcache.revalidate_freq=60
opcache.fast_shutdown=1
opcache.enable_cli=1

你也可以禁用 opcache.save_comments 并且启用 opcache.enable_file_override。 需要提醒的是,在生产环境中使用上述配置之前,必须经过严格测试。 因为上述配置存在一个已知问题,它会引发一些框架和应用的异常, 尤其是在存在文档使用了备注注解的时候。 

vim /usr/local/php7/etc/php.ini
# 加入
zend_extension=/usr/local/php7/lib/php/extensions/no-debug-non-zts-20141001/opcache.so

重启

# killall php-fpm

#  /etc/init.d/php-fpm


如果上图不太明白,可以使用文末Opcache 状态测试代码(https://gist.github.com/ck-on/4959032)进行演示:

OCP - Opcache Control Panel (aka Zend Optimizer+ Control Panel for PHP)
Author: _ck_ (with contributions by GK, stasilok)
Version: 0.1.6
Free for any kind of use or modification, I am not responsible for anything, please share your improvements
 
* revision history
0.1.6 2013-04-12 moved meta to footer so graphs can be higher and reduce clutter
0.1.5 2013-04-12 added graphs to visualize cache state, please report any browser/style bugs
0.1.4 2013-04-09 added "recheck" to update files when using large revalidate_freq (or validate_timestamps=Off)
0.1.3 2013-03-30 show host and php version, can bookmark with hashtag ie. #statistics - needs new layout asap
0.1.2 2013-03-25 show optimization levels, number formatting, support for start_time in 7.0.2
0.1.1 2013-03-18 today Zend completely renamed Optimizer+ to OPcache, adjusted OCP to keep working
0.1.0 2013-03-17 added group/sort indicators, replaced "accelerator_" functions with "opcache_"
0.0.6 2013-03-16 transition support as Zend renames product and functions for PHP 5.5 (stasilok)
0.0.5 2013-03-10 added refresh button (GK)
0.0.4 2013-02-18 added file grouping and sorting (click on headers) - code needs cleanup but gets the job done
0.0.2 2013-02-14 first public release
 
* known problems/limitations:
Unlike APC, the Zend OPcache API
- cannot determine when a file was put into the cache
- cannot change settings on the fly
- cannot protect opcache functions by restricting execution to only specific scripts/paths
 
* todo:
Extract variables for prefered ordering and better layout instead of just dumping into tables
File list filter
