Breve descrizione dei parametri di configurazione.
com.allow_dcom
Quando è impostato a on, il PHP è abilitao ad operare come client D-COM (COM distribuito) e permette agli script PHP di istanziare oggetti COM su un server remoto.
com.autoregister_typelib
Quando questo parametro è impostato a on il PHP tenta di registrare costanti dalla libreria dei tipi dell'oggetto che istanzia, se l'pggetto implementa l'interfaccia richiesta per ottenere le informazioni in oggetto. Se distinguere tra nomi dlle costanti maiuscoli e minuscoli è controllato dal parametro .
com.autoregister_verbose
When this is turned on, any problems with loading a typelibrary during object instantiation will be reported using the PHP error mechanism. The default is off, which does not emit any indication if there was an error finding or loading the type library.
com.autoregister_casesensitive
When this is turned on (the default), constants found in auto-loaded type libraries will be registered case sensitively. See com_load_typelib() for more details.
com.code_page
It controls the default character set code-page to use when passing
strings to and from COM objects. If set to an empty string, PHP will
assume that you want CP_ACP, which is the default
system ANSI code page.
If the text in your scripts is encoded using a different encoding/character set by default, setting this directive will save you from having to pass the code page as a parameter to the COM class constructor. Please note that by using this directive (as with any PHP configuration directive), your PHP script becomes less portable; you should use the COM constructor parameter whenever possible.
Nota: This configuration directive was introduced with PHP 5.
com.typelib_file
When set, this should hold the path to a file that contains a list of typelibraries that should be loaded on startup. Each line of the file will be treated as the type library name and loaded as though you had called com_load_typelib(). The constants will be registered persistently, so that the library only needs to be loaded once. If a type library name ends with the string #cis or #case_insensitive, then the constants from that library will be registered case insensitively.
