How to install ionCube on PHP 5.6 with PHPBrew

I show how to install ionCube on PHP 5.6 but in other case there is no difference and only version of PHP should be changed in command.

Install required PHP version without -debug mode, ionCube does not support it

$ phpbrew install php-5.6.40 +default +mysql +pdo +fpm +gd +gettext +iconv +intl -debug -openssl

Use needable PHP version

$ phpbrew use php-5.6.40

Check your php version with php -v

$ php -v

Download archive with ionCube extensions.
Unpack file _ioncube_loader_lin5.6.so to /home/popov/.phpbrew/php/php-5.6.40/lib/php/extensions/no-debug-non-zts-20131226. Pay attension to files with ts at the end (Thread Safety mode).

Create file 00_ioncube.ini under /home/popov/.phpbrew/php/php-5.6.40/var/db with next content

$ cat /home/popov/.phpbrew/php/php-5.6.40/var/db/00_ioncube.ini
zend_extension=ioncube_loader_lin_5.6.so

Run php -v, you should see that ionCube is enabled

$ php -v
