PHP is a well known general purpose, server side web scripting language. A vast majority of online websites are coded in this language. PHP is ever evolving, feature rich, easy to use and well organized scripting language. Currently PHP development team is working on next major release of PHP, named PHP 7. The current production PHP version is PHP 5.6, as you might already know that PHP 6 was aborted in the past, the supporters of PHP 7 did not want the next important PHP version to be confused with that branch that was killed long time in the past. So it has been decided to name the next major release of PHP as PHP 7 instead of 6. PHP 7.0 is supposed to be released in November this year.
Here are some of the prominent features in next major PHP release.
- In order to improve performance and memory footprints PHPNG feature has been added to this new release.
- JIT engine has been included to dynamically compile Zend opcodes into native machine code in order to achieve faster processing. This feature will allow subsequent calls to the same code so that it may run much faster.
- AST (Abstract Syntax Tree) is a newly added feature which will enhance support for php extensions and userland applications.
- Asynchronous Programming feature will add support for parallel tasks within the same request.
- New version will support for stand alone multi-threading web server so that it may handle many simultaneous requests using a single memory pool.
Installing PHP 7 on Centos / Fedora
Lets see how we can install PHP7 on Centos 7 and Fedora 21. In order to install PHP7 we will need to first clone php-src repository. Once cloning process is complete, we will configure and compile it. Before we proceed, lets ensure that we do have followings installed on our Linux system otherwise PHP compile process will return errors and abort.
All of the above metioned prerequisits can be installed using Yum package manager. The following single command should take care of this:
yum install git autoconf gcc bison
Ready to start PHP7 installation process ? Lets first create PHP7 directory and make it your working directory.
Now clone php-src repo, run following command on the terminal.
git clone https://git.php.net/repository/php-src.git
The process should complete in few min, here is sample output which you should see at the completion of this task.
[root@localhost php7]# git clone https://git.php.net/repository/php-src.git
Cloning into 'php-src'...
remote: Counting objects: 615064, done.
remote: Compressing objects: 100% (127800/127800), done.
remote: Total 615064 (delta 492063), reused 608718 (delta 485944)
Receiving objects: 100% (615064/615064), 152.32 MiB | 16.97 MiB/s, done.
Resolving deltas: 100% (492063/492063), done.
Lets configure and compile PHP7, run following commands on the terminal to start the configuration process:
Here is sample output for ./buildconf command.
[root@localhost php-src]# ./buildconf
buildconf: checking installation...
buildconf: autoconf version 2.69 (ok)
Proceed further with the configuration process using following command:
It will take a sweet amount to time, once completed, you should see output like this:
appending configuration tag "CXX" to libtool
configure: creating ./config.status
