The PHP manual. Assuming that is still your authority on 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]*'"
