SqlLang (sql like methods for Language library)

[eluser]xwero[/eluser]
I've tested the wiki page code, fixed errors, changed the code a bit and the examples.

The biggest changes are the added parameter for the select method that makes it possible to shorten the select by defining a prefix.

Code:

$this->lang->select('one,two','some_long_common_prefix');

And the possibility to replace one placeholder with different values per line

Code:

$this->lang->select('test_var_six,test_var_seven');
$this->lang->set(array('[0]'=>array('me','you'),'[1]'=>array('day','night')));
$this->lang->update();

It would be great if others test it too and report their findings.
