Previous Comments: ------------------------------------------------------------------------ [2009-06-25 11:18:57] RQuadling at GoogleMail dot com Description: ------------ Hi. Would it be possible to have a new magic method allowing a class to handle a request for a constant that has not been defined. <?php class ANSI { static public function __constant($constant) { // Parse $constant to determine response. // e.g. turning COLOUR_BRIGHT_FG_WHITE_RED // into '1;37;41'; } } The values for various constant names are constant. They won't change, but having to manually create all the combinations is a headache. They could be cached internally. So asking for a constant and not finding it would allow the magic method to run and then save it for the next usage. Maybe. Or not. I know this is easily handled as ... ANSI::convertConstantStringToANSISequence(COLOUR_BRIGHT_FG_WHITE_RED) but ANSI::COLOUR_BRIGHT_FG_WHITE_RED is the intent. Even without the caching (which could be done in userland if constants could be added at runtime), then this would be useful. Any takers?
