Language access is enabled in all Class and Methods of appRain. Following method is used to access a code.
$this->__([CODE]);
See below example:
echo $this->__('_HOME');
Common Tips:
Most of the cases we pass a general word in language method and it return the value of the code otherwise it just return same code. So we use like below:
echo $this->__('About Us');
Now if we do not define any "About us" as a code then it will print same "About Us" and if we define "Lorem Ipsume" as a value against it. the method will return the value.
