Reference – What does this symbol mean in PHP?

I am looking at using a custom Taxonomy for a page and reading through the codex I saw code examples using “=>” and “__”

Could someone clarify what these symbols are for and what they are doing?

Thank you!

Answer 1

The => is used for defining the value of a key in an associative array:

$array = array('key' => 'value');

The __() function is used for translations:

$text = __($textkey, $textdomain);
