apc_store

(PECL apc >= 3.0.0)

apc_store Cache a variable in the data store

说明

bool apc_store ( string $key , mixed $var [, int $ttl=0 ] )

Cache a variable in the data store.

Note: Unlike many other mechanisms in PHP, variables stored using apc_store() will persist between requests (until the value is removed from the cache).

参数

key

Store the variable using this name. key s are cache-unique, so storing a second value with the same key will overwrite the original value.

var

The variable to store

ttl

Time To Live; store var in the cache for ttl seconds. After the ttl has passed, the stored variable will be expunged from the cache (on the next request). If no ttl is supplied (or if the ttl is 0), the value will persist until it is removed from the cache manually, or otherwise fails to exist in the cache (clear, restart, etc.).

返回值

如果成功则返回 TRUE,失败则返回 FALSE

范例

Example #1 A apc_store() example

<?php
$bar 
'BAR';
apc_store('foo'$bar);
var_dump(apc_fetch('foo'));
?>

上例将输出:

string(3) "BAR"
