Installation Eclipse PDT, XAMPP (PHP & MySQL), XDebug

XAMPP

Install XAMPP (https://www.apachefriends.org/de/index.html) to the directory „C:/xampp“
Open Config of Apache (File: httpd.conf)

e.g. 
DocumentRoot "D:\05_Insomnia\Humor Nacht\TicketSystem" 
<Directory "D:\05_Insomnia\Humor Nacht\TicketSystem">

php -i > phpversion.txt

Open „C:\xampp\phpversion.txt“ in a text editor
Copy the whole content of the file
Go to the website https://xdebug.org/wizard.php to find the correct xdebug version
Paste the content of the file and click the „Analyze my phpinfo() output“ button.
A download link is generated with the right XDebug version for XAMPP.
Download php_xdebug-xxxxxxxxxxxx.dll
Move the downloaded file to „C:\xampp\php\ext“
Edit „C:\xampp\php\php.ini“ and add the lines:

[Xdebug]
zend_extension = C:\xampp\php\ext\php_xdebug-xxxxxxxxxxxx .dll
xdebug.remote_enable=1
xdebug.remote_port=9000

By default, when you install XAMPP, the password of the „root“ user for MySQL is not set. But it is recommended to set one to protect your database.

Start the Apache Server and MySQL from the XAMPP control panel
Open the Admin Panel of Mysql by clicking on „Admin“-Button under MySQL or open http://localhost/phpmyadmin/
Select the SQL tab to enter a SQL querys.
Enter the following querries. Replace ’new_mysql_password‘ with youtr password and click the Go Button

ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_mysql_password';
ALTER USER 'root'@'127.0.0.1' IDENTIFIED BY 'new_mysql_password';

Now you will see a message saying that the query has been executed successfully.
If you refresh the page, you will be getting a error message. This is because the phpMyAdmin configuration file is not aware of our newly set root password. To set this we have to modify the phpMyAdmin config file.
Therforce go to the XAMPP Control panel and click on the Config-Button under Apache. Choose the config file „config.inc.php“ (or open C:\xampp\phpMyAdmin\config.inc.php)
Search the string $cfg[‚Servers‘][$i][‚password‘] = “; and change it to $cfg[‚Servers‘][$i][‚password‘] = ’new_mysql_password‘;
Set also $cfg[‚Servers‘][$i][‚AllowNoPassword‘] = false;
Save the config.inc.php file and restart the XAMPP server. (stop and start)

Start the Apache Server and MySQL from the XAMPP control panel
Open the Admin Panel of Mysql by clicking on „Admin“-Button under MySQL or open http://localhost/phpmyadmin/
Select the Import tab
Select the exported Database that you want to import
Click OK to import the database
