Opcache Nedir?

PHP 5.5 üzerinde hazır halde gelen opcache temel olarak, filesystem üzerinde bulunan php dosyalarını her requestte okumamak için tasarlanmış bir otomatik low level cache mekanizmasıdır. Php nin 5.5 sürümünü kullanıyorsanız, ve özellikle kapatmadıysanız, muhtemelen siz de bu özelliği kullanabilirsiniz / veya zaten bilmeden kullanıyorsunuzdur.

Tip 1 – Usar la versión más estable de PHP actualmente (5.5)

Para aquellos que están comenzando, es importante arrancar con la última versión estable de PHP (5.5). En los últimos años ha estado en un proceso de continuo desarrollo y mejoras, sobre las caracteristicas de PHP.  Uno pudiera considerar que las mejoras entre versiones son mínimas, pero en realidad se reflejan en un notable incremento en el rendimiento del sistema.

Cualquier detalle en…

Si ya tienen instalado php 5.4 omitan el paso siguiente. Para ver su version de php escriban en el terminal:

php -v

Añadimos el nuevo origen:

sudo add-apt-repository ppa:ondrej/php5

Instalamos PHP 5.4:

sudo apt-get install php5

Pude que tras la instalación obtentas algún mensaje del tipo “… Unable to load dynamic library …”. Los mensajes se deben a que intenta cargar algún módulo que no se encuentra en la ruta indicada por el php.ini. Lo recomendado es revisarlo y ver que otros ficheros .ini carga mediante phpinfo(). En mi caso, tuve que reinstalar pdo para la conexion a mysql y xdebug para lo cual también necesite perl/pecl.

Ahora si procedemos a instalar php 5.5

La versión más reciente (es del 20 de Junio) es la 5.5.0. Si queremos compilarla o añadir un nuevo origen de Ondřej Surý para la esta versión:

Añadimos el nuevo origen:

sudo add-apt-repository ppa:ondrej/php5-experimental

Recently I found out that (yes just out because i am n00b) nginx+php-fpm through unix sockets has really good performance boost for php execution. I tried to use the builtin packages of ubuntu for both php-fpm and php-cli. But the worst thing about them that they are still php5.3. I want to use php5.5, because at like i mentioned at my previous post, I started to use php5.5 specific apis. So, i decided to compile php5.5 from scratch. It seems really hard but, actually compiling from scratch gives you the power of using only necessary extensions of php.

What i understood from php.net documentation is that now the php-fpm is builtin to the php source code. it requires the necessary keywords in the configure phase. My php ./configure statement is like this:

'./configure' \ '--enable-opcache' \ '--prefix=/opt/php' \ '--with-mysql=mysqlnd' \ '--with-mysqli=mysqlnd' \ '--with-tidy=/usr' \ '--with-curl=/usr/bin' \ '--enable-openssl' \ '--with-openssl' \ '--with-zlib-dir=/usr' \ '--with-xpm-dir=/usr' \ '--with-pdo-mysql=mysqlnd' \ '--with-xsl=/usr' \ '--with-ldap' \ '--with-xmlrpc' \ '--with-iconv-dir=/usr' \ '--with-snmp=/usr' \ '--enable-exif' \ '--enable-calendar' \ '--with-bz2=/usr' \ '--with-mcrypt=/usr' \ '--with-gd' \ '--with-jpeg-dir=/usr' \ '--with-png-dir=/usr' \ '--with-freetype-dir=/usr' \ '--enable-mbstring' \ '--enable-zip' \ '--with-pear' \ '--with-libdir=/lib/x86_64-linux-gnu' \ '--with-config-file-path=/opt' \ '--enable-fpm' \ '--with-fpm-user' \ '--with-fpm-group' \ '--enable-sockets' \ '--with-sockets'

i am installing php to the /opt/php/ just for personal habits. So, in order to have the php as global, you can type export PATH=/opt/php/bin:$PATH to your ~/.bashrc or ~/.zshrc or whatever shell type you're using.

this will give you many errors if you don't have the necessary libraries are not installed in your computer. To get around from this you can execute this command as root in ubuntu12.04:

apt-get build-dep php5

actually i didn't know about this command before, i manually apt-get'ed the necessary libraries one-by-one. So, i don't know if this command is really doing what is supposed to do. So, if you still get errors while you are configuring php, simple google search will help you. afaik:

apt-get install lib<library-name>-dev

command will work with almost every dependency.

one last thing, if you are compiling for your development environment and want the xdebug to work with, you can type the following as root on command line:

pecl install xdebug

this will install the xdebug, and the necessary compilings, but you still may need to make necessary edits to the php.ini file. if you're having errors about xdebug, add the following to your php.ini file:

zend_extension=xdebug.so

Today i started a fresh laravel 4 for our newest product, which has only a code name of 'ProjectX'. Recently, i found out that php5.5 has been released, and thrilled by its builtin support of Zend opcache. Which gave me 500% performance boost.

Since i started to use php5.5, i saw that there is a new API for class names. Because, I started to use my own namespaces with the models, i've been hardcoding the name of the classes with full namespaces in them, when i need to make model relationships. But, now whenever i use:

use ProjectX\Models\User;

I now can do

User::class

and it will return, ProjectX\Models\User
