Put this in your root directory:
<?php
phpinfo();

If you are using new version of xampp.
Try http://localhost/dashboard/phpinfo.php
Put this code in your root directory or htdocs folder of xampp:
<?php phpinfo(); ?>- Save it as phpinfo.php and point your browser to it (this could be http://localhost/phpinfo.php)

You just need to find out where is your PHP folder.
- If you are using XAMPP or WAMP then you will see a php folder.
- You just need to go into the php folder using your cmd using command
cd \xampp\php (FOR XAMPP)
cd \wamp\php (FOR WAMP)
- And then just type in this command
php -v
- Then you will see something like
PHP 5.6.11 (cli) (built: Jul 9 2015 20:55:40) Copyright (c) 1997-2015 The PHP Group Zend Engine v2.6.0, Copyright (c) 1998-2015 Zend Technologies
In my case I have installed XAMPP for Linux (LAMPP) in Ubuntu 18.10
How can you know it?
- Try to go to /opt/lampp
- If you can, it means Xampp for Linux it's installed, but if you want to know the version, in the same path of step 1, put in your command line ./xampp status You will know XAMPP for Linux version and Apache, MySQL and ProFTPD status (running or not).
Know PHP version
cd /opt/lampp/bin
./php -v
Know MySQL (MariaDB) version
cd /opt/lampp/bin
./mysql --version
Know Apache version
cd /opt/lampp/bin
./apachectl -v
I hope helps somebody
./xampp status image
You have to understand this :
1) LAMP
For LAMP setup, you have to install PHP, Apache and Mysql packages separately. In LAMP you don't get anything to manage your server in GUI way.
For Ex: To start apache server you have to type command in terminal.
To start apache : sudo service apache2 start
For installing LAMP refer :
https://www.digitalocean.com/community/tutorials/how-to-install-linux-apache-mysql-php-lamp-stack-on-ubuntu
2) XAMPP
It is a complete package which comes bundled with PHP,Apache, Mysql etc in a single installation. It gives you a control panel from which you can manage your server and configuration files.It is something of this sort.

For XAMPP : https://www.apachefriends.org/download.html
If you don't find xampp control panel in your system, this means you have a LAMP setup. i.e : first option.
Run in command line
<xampp_dir>\apache\bin\httpd -v
It prints Apache version.
For example I had installed XAMPP to C:\Aplikace\xampp directory and type into Command Line
C:\Aplikace\xampp\apache\bin\httpd -v
that responsed

- Go to xampp folder where you installed xampp
- Find apache?
- xampp->apache->bin->httpd->right click->properties->details->version find php version in xampp
- xampp control panel which, after the complete installation, contains start, stop, config, etc.
- There you find shell-> click->type php-v
- mariaDB version in xampp?
- Type localhost/phpmyadmin after installation on url
- Find sql
- Type select version(); and hit enter
Please note
This answer is not valid for new version of XAMPP.
First, you'll need to stop Apache from XAMPP. Then,
Go go cmd and switch to your XAMPP folder. For example, if your XAMPP folder is in C:\
C:\>cd C:\XAMPP
In this folder is a file named php-switch.bat, run from the command line. If not, you can also run php-switch.bat directly.
You'll see the version you are now on, and procedure to switch. For example, type 4 to switch PHP 4 then follow the procedure.

PHP 4 will install in your XAMPP\PHP directory and successfully switch. then re-enable the Apache.
The best method is to change the PHP settings in
/apache/conf/extra/httpd-xampp.conf
to reflect the new version of PHP you want to use
In my case I unpacked PHP5.4 to C:\XAMPPLITE\PHP5.4 and then updated key lines in this file such as:
SetEnv PHPRC "C:\\xampplite\\php5.4"
LoadFile "C:/xampplite/php5.4/php5ts.dll"
PHPINIDir "C:/xampplite/php5.4"
You also need to ensure that the correct version of php5apache2_2.dll is installed
To ensure this I copied the new version of php5apache2_2.dll to the Apache modules directory with a unique name, and then modified the configuration to match that:
copy php5.4\php5apache2_2.dll apache\modules\php5apache2_2-5_4.dll
and in the httpd-xampp.conf file
LoadModule php5_module modules/php5apache2_2-5_4.dll
