Description:
------------
The documentation on user-defined functions (http://www.php.net/manual/en/language.functions.php) does not specify the format of a legal function name (wheras http://www.php.net/manual/en/language.variables.php does  contain a regexp specifying legal variable names, for example.)

Can such information be added?

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

"Function names follow the same rules as other labels in PHP. A valid function 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]*."
