More than likely though, it's available to you, but you're not running it yet.
If you're seeing an error message like the following, then you're running PHP 5.2 or lower.
Parse error: syntax error, unexpected T_STATIC, expecting ')' in ...\wp-content\plugins\custom-bulkquick-edit\lib\aihrus\class-aihrus-common.php on line 44
If you don't believe it, then create a `phpinfo.php` file in your website root with the code below. Then using your web browser, call it via `http://example.com/phpinfo.php` to see which PHP version you're running.
<?php phpinfo(); ?>

DIY – Fix The Problem
Which PHP Version?
PHP 5.3+ means PHP 5.3 or newer is required. So PHP 5.3, 5.4, or 5.5 should be fine. Truthfully, you should use PHP 5.5 so that you don't have to worry about this for a few more years again.
On many web hosts, just add the following code to the top of your `.htaccess` file in your website root directory.
Select option 5.3 or newer for PHP Version from the drop down
Why PHP 5.3 or newer?
Aihrus is moving forward in developing using current technology and techniques. As such, at some points in time during software development a crossed bridge must be burned. So that we can use things like…
Per PHP: If you are using these (end of life) releases, you are strongly urged to upgrade to a current version, as using older versions may expose you to security vulnerabilities and bugs that have been fixed in more recent versions of PHP.
After Updating, Clear Your Caches!
Still No Go…
The condition you mention is rare, but does happen when the server's main PHP version isn't PHP 5.3+ and the PHP 5.3+ configuration is via .htaccess or the like. A server change so that it's providing PHP 5.3+ by default will resolve things.
Wasn't Testing Done?
These plugins go out to 30+ beta testers, several live and development sites, a multitude of tests are run, and coding standards are met before any release happens. Frankly, software releases are a major pain because of so much hassle in getting good enough testing completed.
