I have migrated my project from AWS to Google Cloud. I had a working application earlier, but now after migrating to GCP, mysqli_connect no longer seems to work.
So far, I have installed the following:
php-mysql-5.4.16-42.el7.x86_64
php-pdo-5.4.16-42.el7.x86_64
php-5.4.16-42.el7.x86_64
php-common-5.4.16-42.el7.x86_64
php-cli-5.4.16-42.el7.x86_64
mariadb-libs-5.5.52-1.el7.x86_64
mariadb-5.5.52-1.el7.x86_64
I am able to access MySQL using terminal but unable to connect to the remote database (on AWS RDS) using PHP. The RDS Database doesn't have any restriction on IP Connection and is open to the world. I have tried removing PHP, MySQL, MariaDB completely, however, no success. The script to connect to the database is unchanged since migration. Other functions such as mysqli_fetch_assoc and mysqli_query are not throwing any error. Here is the content of mysqld_log:
170329 07:20:15 mysqld_safe mysqld from pid file /var/run/mysqld/mysqld.pid ended

You write that you use mysqli_connect, but you have installed php-mysql-5.4.16-42.el7.x86_64 (Note: no 'i'). You need the package for mysqli in order for PHP to connect.

you can use wamp server it`s alternative of xampp and you can run both php 5.6 and php7
in new version

I try starting the xampp mysql service and i failed. I already disable mysql service in the windows service panel and i change the ports 3306 to 3309 in the my.ini file.

Question:
Why I change to port 3309 and it is still connecting to the port 3306?
I already disable other mysql service so even though it is 3306 and it should still able to connect
I just start mysql but there is some error. I have config my.cnf and descrease innodb_buffer_pool_size to 64 MB but nothing happend.

These are not error's they are [Note] i.e. informational messages.
If the WampServer icon is Orange, then it is probably Apache that has not started.
Check what is using port 80 like so:
left click the Wampmanager icon ( thats the icon in the system tray ) -> Apache -> Services -> Test port 80
If it reports anything other that
Your port 80 is actually used by :
Server: Apache/2.?.?? (Win32) PHP/5.?.??
Where the version numbers match what you have installed then something else has captured port 80 and needs to be Uninstalled, reconfigured or disabled.
