Double Underscore in PHP?

Question

What does the double underscores in these lines of PHP code mean?

$WPLD_Trans[\'Yes\']=__(\'Yes\',$WPLD_Domain);
$WPLD_Trans[\'No\']=__(\'No\',$WPLD_Domain);         


        

Answer 1

Strictly speaking, it means nothing in PHP as it is not a pre-defined function. However, in many frameworks, like CakePHP, and other libraries the double underscore is a function used for translating strings based on the user's language/locale preference.
