Answer 1

It seams your PHP Version is too low for xdebug:
Your PHP: "PHP Version: 5.6.32"
xDebug log said: "PHP versions below 7.0 are not supported."
So, after you upgrade you PHP version and successfully install xdebug, you should see (example):
# php -v
HP 7.2.3 (cli) (built: Mar 8 2018 10:30:06) ( NTS )

I wanted to update this question because it is still possible to install XDebug against 5.6 and may still be necessary for legacy applications.
The wizard won't help you if you need to install XDebug for an older version of PHP (<7); you'll have to read the documents and work out the process yourself.
At https://derickrethans.nl/xdebug-php5.html the author states that the older source is available for downloading and using with older versions of php, and that 2.5 is the last version to work with PHP 5.6. You can download xdebug 2.5 from https://xdebug.org/download.php (or other versions as required).
The instructions on how to do this are on the XDebug website but maybe a little hard to grasp. A rough guide for installing installing on a CentOS 7.5 with Php 5.6 would be:
wgets https://xdebug.org/files/xdebug-2.5.5.tgz
tar -xvzf xdebug-2.6.0.tgz
cd xdebug-2.6.0
phpize [troubleshoot: yum install php-devel]
./configure --enable-xdebug
make
create a directory keep the xdebug module: mkdir /usr/php/xdebug/255
cp modules/xdebug.so /usr/php/xdebug/255
Find the active php.ini using php -i or phpinfo() in a script.
Restart the webserver: sudo service httpd restart
Make sure XDdebug is reported as enabled.
Edit php.ini: sudo nano /etc/php.ini
Add (or whatever your preferred options are) to php.ini:
zend_extension="/usr/php/xdebug/255/xdebug.so"
xdebug.remote_enable=1
xdebug.remote_autostart = 1
xdebug.remote_port="9000"
xdebug.remote_connect_back=on
Configure your client to connect. I've had this working with vscode.
