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. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
