They must mean labels as in "general naming convention rules for
programming"... Like not naming a variable/function "label" with a number at
the front.
Here's a page about variables:
http://www.php.net/manual/en/language.variables.basics.php
Variable names follow the same rules as other labels in PHP. A valid
variable name starts with a letter or underscore, followed by any
number of letters, numbers, or underscores. As a regular expression,
it would be expressed thus: '[a-zA-Z_\x7f-\xff][a-zA-Z0-9_\x7f-\xff]*'
But I agree though, it would be nice if "label" was defined somewhere
in the docs.
