Change htdocs path in XAMPP

Here in this example, I am showing you to change the php project directories path from /opt/lampp/htdocs to /var/www

1) Open file /opt/lampp/etc/httpd.conf and change following line

DocumentRoot "/opt/lampp/htdocs"
to

DocumentRoot "/var/www"

2) Now search following line in same file (/opt/lampp/etc/httpd.conf)
and change

# This should be changed to whatever you set DocumentRoot to.
<Directory "/opt/lampp/htdocs">

to

# This should be changed to whatever you set DocumentRoot to.
<Directory "/var/www">

(Above line is commented, it has been mentioned to find directive easily)

3) Restart the XAMPP.

4) If virtual hosts have been defined, change the path in /opt/lampp/etc/extra/httpd-vhosts.conf too.
Otherwise above steps will not work.

or if you want to remove virtual hosts, just comment following line in /opt/lampp/etc/httpd.conf

# Include etc/extra/httpd-vhosts.conf

5) Restart the XAMPP.

6) After following above process, if it throws php code in browser.
Uncomment following line in the file /opt/lampp/etc/httpd.conf

Include etc/extra/httpd-xampp.conf

This line should not be commented. It means there should be no Hash '#' symbol at start of the line.

7) If it gives Internal Server Error or Server Error.
Comment following line in the file /opt/lampp/etc/httpd.conf

# Include etc/extra/httpd-vhosts.conf

& Restart the XAMPP.
