How to use different PHP versions at the same time for different hosts in Open Server?

Question

PHP

I work on Windows 10 x86, Open Server 5.2.6 Ultimate.
Installed FastCGI and PHP-NTS 5.2-7.1
I don't want to constantly switch the PHP version, I would like to set it up and forget it once.
Some projects are tied to a specific version of PHP and do not work on new ones. For example, there is a project with Zend Guard Loader 5.3 bytecode and PhpMyAdmin that requires PHP 5.5
On many hostings, you can set the PHP version via .htaccess AddHandler like this:

# To switch to PHP 4.4:
AddHandler application/x-httpd-php4 .php .php4 .php3
# To switch to PHP 5.0:
AddHandler application/x-httpd-php5 .php .php5 .php4 .php3
# To switch to PHP 5.1:
AddHandler application/x-httpd-php51 .php .php5 .php4 .php3
# To switch to PHP 5.2:
AddHandler application/x-httpd-php52 .php .php5 .php4 .php3
# To switch to PHP 5.3:
AddHandler application/x-httpd-php53 .php .php5 .php4 .php3
# To switch to PHP 5.4:
AddHandler application/x-httpd-php54 .php .php5 .php4 .php3
# To switch to PHP 5.5:
AddHandler application/x-httpd-php55 .php .php5 .php4 .php3
# To switch to the secure PHP 5.2 with Suhosin patch:
AddHandler application/x-httpd-php52s .php .php5 .php4 .php3

If it doesn't work inside Open Server, then how do you do it?

Answer 1

There is a save settings. Switch between them, it's 1 click. You still don't work on 15 projects at the same time. And the presence of a newer version does not prevent the launch of projects written under the old one. You made a problem out of nothing.
