Install New version xampp in your Ubuntu machine

xampp.txt

First go to here https://www.apachefriends.org/download.html
Now copy the url 
You will get the URL like this 
https://www.apachefriends.org/xampp-files/7.1.4/xampp-linux-x64-7.1.4-0-installer.run

Now open your terminal and run the following command 

wget https://www.apachefriends.org/xampp-files/7.1.4/xampp-linux-x64-7.1.4-0-installer.run

After that run this 
sudo su

Next Step bellow these 

chmod +x xampp-linux-x64-7.1.4-0-installer.run
./xampp-linux-x64-5.6.20-0-installer.run

Now you can run the xampp by this command 

sudo /opt/lampp/lampp start 

If you want to stop then just replace the start to stop word :P 

all right, Now we need to give permission for accessing htdocs folder and where you can create file and folder. 

you can give permission htdocs fodler by this command 

sudo chmod -R 777 /opt/lampp/htdocs

Last Step you need to restart your xampp . 

you can do it by this command

sudo /opt/lampp/lampp restart

That's all my dear fans :)
