PHP Connect to MySQL Database in Other Server

Question

I have 2 shared hostings: 1.1.1.1 and 2.2.2.2
I have a PHP script in 1.1.1.1 that connect to a database in 2.2.2.2
In Remote Database Access Hosts (2.2.2.2) I put '%' means that I allow connection from any IP
Database username in 2.2.2.2: foo
Database password in 2.2.2.2: bar

My PHP script:

mysql_connect('2.2.2.2:3306', 'foo', 'bar', true);

I got this error:

Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on '2.2.2.2' (4)

Answer 1

If Your servers connected, make sure that on server 2.2.2.2 "my.cnf" mysql configuration file allows remote connections. This might help you.

Answer 2

Thanks for your help. It's about firewall, I contact my hosting and they fixed it for me.
