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 ONE, TWO, THREE;
?>

以上例程会输出：
