Problemer med script der virkeri PHP4, men ikke i PHP5

kan det være at nogle af indstillingerne er anderledes i den nye installation af PHP?
har du tjekket at error reporting er slået til og viser ALT så du kan få en ide om problemet?
error_reporting(E_ALL);

Det er koden for selve calenderklassen

Den bliver kaldt fra en anden klasse der inkluderer den den med require()...

Den bliver kaldt med

$cal = new Calendar();
echo $cal->getMonthView($month, $year)

Jeg har kørt hvor al errorreporting var slået til - slog det til på servniveau, men stadig uden at det kastede en fejl af sig.

serverniveau...

du skriver at den undlader at vise al kode, betyder det at du har en hvid side eller?

er det en nøjagtig kopi du har pastet herind, for jeg kan se at der mangler en '}' til den nederste klasse

og det skal lige siges at med det kode du har givet mig her så virker det efter den '}' er tilføjet. Det ser lidt underligt ud, men der er da output og jeg bruger php 5.2.0.

Min fejl, kaldet er
$cal = new MyCalendar();
echo $cal->getMonthView($month, $year)

det er det som ikke virker...

Det er vidst en længere omskrivning.
begynd at læse her: http://dk2.php.net/manual/en/language.oop5.php

Det var ikke for at virke kort for hovedet i min sidste kommentar, jeg havde bare noget andet jeg skulle nå, så det blev lidt kortfattet.
en af de ting du skal have gjort er at sætte public og private på variabler og funktioner og variablerne skal defineres. Der er muligvis mere, men jeg har ikke lige så meget styr på forskellen mellem OOP i php4 og php5. Har nemlig aldrig brugt det før php5

Nu har jeg ikke læst din kode igennem. Men hvis du bruger php's indbyggede calendar-funktion, skal den først kompileres med ind.

Tak for de gode svar. Jeg undlod at omskrive koden, da jeg ikke var sikker på de sideeffects det evt. kunne give, så vi satte istedet serveren op, så den kan køre både php4 og php5. Hvis du poster noget sw_red_6 skal du få nogle point.

Lukketid!
