apc_load_constants

Loads a set of constants from the cache (PECL)
bool apc_load_constants ( string key [, bool case_sensitive] )

参数

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.

返回值

如果成功则返回 TRUE,失败则返回 FALSE
