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.

解决方法
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.
