我刚刚用

PHP Handler FastCGI安装了APC.但似乎Cache永远不会起作用.

if(($t=apc_fetch('key_4321'))===FALSE){

$t=time();

apc_add('key_4321', $t, 24*60*60);

}

echo $t;

几乎每次我运行它我都有不同的时间戳.只有几次它仍然是相同的结果.可能的原因是什么？

我正在使用PHP版本5.3.21,而服务器API是CGI / FastCGI.

Server Software Apache/2.2.23 (Unix) mod_ssl/2.2.23 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 mod_fcgid/2.3.6

以下是我的APC设置.

最佳答案 在大型网站上使用APC~我强烈建议人们不要使用APC.

相反,我想建议您使用XCache

它与APC相同,但不会一直崩溃和断块.
