I have 2 servers with the following settings:
Server 1:
PHP 5.3.10
Apache 2.2.22
MySql 5.5.43
Ubuntu 12.04.5 LTS
Server 2:
PHP 5.6.9
Apache 2.4.7
MySql 5.5.43
Ubuntu 14.04.2 LTS
I'm using the Yii framework.
The problem is that on server 1 the word "dog" appears normally, on server 2 it appears "dog".
Server 2 is a copy of server 1 but we changed Apache / PHP / OS.
What might be the source of the problem? What version of the operating system?
