I changed the phpmyadmin mysql port number, and now I can't log in

Question

I have a mysql server running locally on port 3307, which I can connect to just fine through command line

mysql -P 3307 -h 127.0.0.1 -u root -p

In order to access this database through phpmyadmin, I changed these settings in /etc/phpMyAdmin/config.inc.php

$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['port'] = '3307';

However when I try to log in, i get an error saying "cannot log in to the mysql server". Is this maybe an issue with apache blocking the login?

I have tried to connect using both localhost/phpMyAdmin and 127.0.0.1/phpMyAdmin.

Below is my config.inc.php file

<?php

 * configuration. For easier setup you can use "setup/".

@Martin If something else were using it, he would get an error when trying to connect to it from the CLI. — Barmar
this search shows many previous questions about this error, probably one of them will be helpful. — Barmar
Is your web server listening on localhost? if you do telnet 127.0.0.1 80 and hit enter a couple of times do you get an apache message about a bad request, or does it not connect? — Terry Carmen
@TerryCarmen I get a bad request message, "Your browser sent a request that this server could not understand" when manually closing the connection after a few minutes. Letting it run on its own leads to "connection closed by foreign host", and nothing else. Is that the expected result? — Valley

Goto xampp>phpMyAdmin Directory.

Find the config.inc.php file.

Now change this line:

$cfg['Servers'][$i]['host'] = '127.0.0.1';

To

$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

OR

open my.ini file located in the XAMPP/mysql/bin/ directory, find words that contain number 3306, eq: port = 3306, then replace it with your own, such as 3307.

I changed the phpmyadmin mysql port number, and now I can't log in
