apc_load_constants

(PECL apc >= 3.0.0)

apc_load_constants Loads a set of constants from the cache

说明

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

Loads a set of constants from the cache.

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

成功时返回 TRUE, 或者在失败时返回 FALSE

范例

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 
ONETWOTHREE;
?>

以上例程会输出:
