apc_load_constants Loads a set of constants from the cache

Beschreibung

bool apc_load_constants ( string $key [, bool $case_sensitive = true ] )

Loads a set of constants from the cache.

Parameter-Liste

key

The name of the constant set (that was stored with apc_define_constants()) to be retrieved.

case_sensitive

The default behaviour for constants is to be declared case-sensitive; i.e. CONSTANT and Constant represent different values. If this parameter evaluates to FALSE the constants will be declared as case-insensitive symbols.

Rückgabewerte

Gibt bei Erfolg TRUE zurück. Im Fehlerfall wird FALSE zurückgegeben.

Beispiele

);
apc_define_constants('numbers'$constants);
apc_load_constants('numbers');
echo 
ONETWOTHREE;
?>

There doesn't seem to be a way to store constants that have already been defined. This function, apc_define_constants(), does both things: (1) defines a constant, and (2) stores the constant in the cache. This is unfortunate, since it introduces the requirement to handle constant definitions differently when APC is not available.

(If this function had a "$do_not_define" parameter, or the like, that would give it more flexibility. I suppose filing a bug report would be a step in the right direction to getting this idea considered.)
