[ Application ] Math

[pate33]

Hi,

hab grad nix zu tun im geschaeft und wollt mal wieder meine kopfrechenkuenste etwas aufbessern... *g*

naja, ich hab mal diese kleine applikation geschrieben, mit welcher man ein wenig trainieren kann... :D

einfach copy & paste uebernehmen... ich ´freeware´... *gg* ... die datei sollte ´math.php´ heissen...

greetz

(fixed version (by cyrus)) leider ohne farbige tags, da mit der php funktion die br tags nicht dargestellt werden... :(

viel spass damit.

was mich nun dabei interessieren wuerde:

wie schreib ich sowas &acute;objekt orientiert&acute; ?

will das mal an nem praktischen beispiel ueben... :D

so hab dann mal bisschen gebugfixed :D

@silencer: Meiner Meinung nach lässt PHP nur eine gerine Objektorientierung zu, was sie dann auch wieder nicht nötig macht! :)
