No info on php.net but here is a quote from http://www.smartwebby.com/PHP/variable.asp
< Limitations in Variable Naming: PHP has no limit < on the length of variable name as in the case of < other programming languages. The variable name < must start with a letter or underscore. The variable < name must be a combination of letters, numbers and < underscores. Other characters such as *, +, #, @ are < not allowed and causes error if used. But I really wonder... I hardly name my variables with more than 32 letters. My average is 14 letters. And it's still easy to understand. ------------------------ Yahoo!
