Capitals in function names v get_class_methods

Dear all, I've just read in the pear guidelines that capitals are encouraged for function and variable names. e.g. thisIsMyFunction($myVariable) {

    // etc

} I've recently re-written a configuation language which is extensible based purely on the fact that get_class_methods returns the available functions. But, it returns them in lower case. Surely it would be better to: i. write get_class_methods as case sensitive (perhaps it's lower than this function though) ii. write all function in lower case ?? dan
