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.)
apc_load_constants
(PECL apc >= 3.0.0)
apc_load_constants — Loads a set of constants from the cache
설명
bool apc_load_constants
( string
$key
[, bool $case_sensitive = true
] )Loads a set of constants from the cache.
인수
-
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
FALSEthe constants will be declared as case-insensitive symbols.
반환값

예제
Example #1 apc_load_constants() example
<?php
$constants = array(
'ONE' => 1,
'TWO' => 2,
'THREE' => 3,
);
apc_define_constants('numbers', $constants);
apc_load_constants('numbers');
echo ONE, TWO, THREE;
?>
위 예제의 출력:
123
참고
- apc_define_constants() - Defines a set of constants for retrieval and mass-definition
- define() - Defines a named constant
- constant() - 상수 값을 반환합니다
- Or the PHP constants reference
