PHP version via .htaccess
We have 3 different versions of PHP installed, which we recommend to use.
DThe different versions can be used simultaneously in the same web.
How to use for example PHP 5.6.x in your web, is described below.
1. Available php versions
PHP 5.6.x / 7.0.x / 7.1.x (all compiled with GD)
2. php applications
If you have several PHP applications (e.g. a CMS, forum, etc.) that should run on PHP 5.6.x / 7.0.x / 7.1.x, then you can realize this with one .htaccess file each.
3. create .htaccess
Create a file with the Notepad or a similar editor (in Windows: Start - Run - "notepad" - OK) with one of the following 3 lines:
Action php /cgi-php56/php
AddHandler php56 .php
Action php /cgi-php7/php
AddHandler php7 .php
Action php /cgi-php71/php
AddHandler php71 .php
Save the file under File - Save as. The file name would be .htaccess, the file type would be All files and with the encoding ANSI.
4. File upload
Now load this .htaccess file into the directory where the .php files should be interpreted as PHP 5.6.x / 7.0.x / 7.1.x.
