Open XAMPP Control Panel, hit on the "Help" button and then "View ReadMe" ... It'll open a Notepad file having the first line as:

"###### ApacheFriends XAMPP Version x.y.x ######"

where x.y.z is the XAMPP version!

Put this in your root directory:

<?php
phpinfo();
?>

Save it as phpinfo.php and point your browser to it (this could be http://localhost/phpinfo.php)

• More information (you can get much more information than just the version).
• Example (random image):

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

If you are using new version of xampp.

Try http://localhost/dashboard/phpinfo.php

That last bit is not guaranteed to work across multiple versions, though.

Personal opinion -- the catalina solution should be perfectly fine.

P.S. your (XAMPP) Tomcat home folder usually lies in $XAMPP/tomcat/
