ZF-209: Function names and use of TRUE and FALSE
I'm slightly confused by function names given meaning numbers. It seems sometimes 'digit' is used and other times 'number'. Also they are shortened.
Functions: isDigits() isAlnum() getDigits() getAlnum() Should be isNumeric() isAlphanumeric() getNumbers() getAlphanumerics()
Also TRUE and FALSE seems to have been used routinely over true and false, personally I think the former is misleading as it implies they are constants and not language keywords. From what I can see the Zend Coding Standard doesn't specify which is acceptable.
