apc_load_constants

(PECL)

apc_load_constants --  Loads a set of constants from the cache

说明

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。

范例

例子 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;
?>

上例将输出：

there is a bug in version 3.0.10 that keeps it from working! it always returns false and doesnt load the constants (even though apc_define_constants saved it correctly in memory)!

i spent hours looking for this one, went throught dozens of google-result-pages, asked other people, looked through the coed for obvious error... hope it helps others
