The expression
$args of type array is implicitly converted to a boolean; are you sure this is intended? If so, consider using ! empty($expr) instead to make it clear that you intend to check for an array without elements.
This check marks implicit conversions of arrays to boolean values in a comparison. While in PHP an empty array is considered to be equal (but not identical) to false, this is not always apparent. Consider making the comparison explicit by using

The expression
$this->current_language of type false|string is loosely compared to false ; this is ambiguous if the string can be empty. You might want to explicitly use === false instead.
In PHP, under loose comparison (like For '' == false // true
'' == null // true
'ab' == false // false
'ab' == null // false
// It is often better to use strict comparison
'' === false // false
'' === null // false
