Ask the meaning of a wordpress statement-php Tutorial

Ask the meaning of a wordpress statement $ templates = array ();

If (''! ==$ Name)
$ Templates [] = "header-{$ name}. php ";

$ Templates [] = 'header. php ';

This program judges whether $ name is null. if not, assign $ templates [] "header-{$ name}. php"

But then $ templates [] = 'header. php'; then templates is finally header. php.

What is the role of the previous judgment?

Thank you.

$ Templates []; // adds a value to the array, not a value;
So in $ name! = '', There are two values in the $ templates array
