(No version information available, might be only in CVS)

main — Riferimento a main()

Descrizione

Non esiste una funzione main() tranne che nel sorgente PHP. Dal PHP 4.3.0 è stata introdotta nel sorgente una nuova tipologia di errore gestibile (php_error_docref). Una caratteristica di questa è quella di fornire il link alla pagina del manuale nel messaggio di errore nel caso in cui la direttiva html_errors (on per default) e docref_root (on per default dal PHP 4.3.2) siano impostate.

Qualche volta gli errori fanno riferimento alla pagina del manuale per la funzione main() ed è per questo che esiste questa pagina. Si prega di aggiungere nei commenti sottostanti quale funzione PHP ha cusato l'errore che punta a main(), e questo sarà prontamente corretto e documentato.

Errori noti che punatno a **main()**
Nome della funzione	Non punta più qui da
include()	4.3.2
include_once()	4.3.2
require()	4.3.2
require_once()	4.3.2

if like me, you're working inside a framework where you can't require the file with the class definition before session_start is called, I found the following workaround:



$whatever = unserialize(serialize($_SESSION['whatevever']));



dirty hackish, but works.

In addition to Maurice's comments:



the "The script tried to execute a method or access a property of an incomplete object" message can appear also if you store your objects in session, and rename class during that session.



For example, you have class "class_name", and there is a class variable "$class_var = new class_name". 



If you decide to rename your class, you would have "$class_var = new class_new_name".



This re-naming will result in abovementioned error message if you store $class_var in session.



Solution: clean-up session variable, then error disappears.

To put it simple: main() refers to anything running in the current PHP script file that isn't part of any function.

Additional note about what Maurice said: you can also use an __autoload function which will get called as the session/var is unserialized.



This will allow you to not preload all possible classes before loading a session, and let them be loaded dynamically. Check http://php.net/oop5.autoload for more details about this magic function.

Notice: main() [function.main]: The script tried to execute a method or access a property of an incomplete object. Please ensure that the class definition "<classname>" of the object you are trying to operate on was loaded _before_ unserialize() gets called or provide a __autoload() function to load the class definition in <filename> on line <line>



You get this error if you have and object in your $_SESSION array and you call session_start() before you have loaded your included classes.
