What does PHP's underscore function do?

Question

Quick question.

What does this function do? _()

Can you link me to the relevant documentation as searching for "_" is nigh on impossible.

Thanks.

Answer 1

If you open http://www.php.net/_ you get to the documentation of the _() function and see its for localization stuff (gettext).

Answer 2

Note sure I understand your question but here are some explanations for common scenarios.

• PHP Magic Method
• Old PHP4 method of defining private methods
• gettext() alias used for localisation

Answer 3

It's an alias for the gettext() function.

Answer 4

_() is an alias of gettext().
