Question

我在mac osx 10.7.3上安装了Xcache 2.0.0模块，将其配置添加到php.ini，如下所示

; zend_extension = /opt/local/lib/php/extensions/no-debug-non-zts-20090626/xcache.so extension = xcache.so
[xcache]
xcache.shm_scheme =        "mmap"
xcache.size  =               64M
xcache.count =                 1
xcache.slots =                8K
xcache.ttl   =                 0
xcache.gc_interval =           0
xcache.var_size  =            32M
xcache.var_count =             1
xcache.var_slots =            8K
xcache.var_ttl   =             0
xcache.var_maxttl   =          0
xcache.var_gc_interval =     300

xcache.mmap_path =    "/dev/zero"
xcache.coredump_directory =   ""
; per request settings
xcache.cacher =               On
xcache.stat   =               On
xcache.optimizer =           Off    

xcache.test =                Off
xcache.experimental =        Off

[xcache.coverager]
xcache.coverager =          Off

; ini only settings xcache.coveragedump_directory = ""

当我尝试使用以下功能

时

$test = "Hello";
xcache_set("test", $test );

出现此错误

警告：xcache_set（）[function.xcache-set]：xcache.var_size为0或者太小而无法启用var数据缓存

但正如您从phpinfo（）

中看到的那样，正确配置了Xcache设置

我也遇到了同样的问题，但是通过更改xcache.mmap_path

的值来实现它

xcache.mmap_path =    "/tmp/xcache"

为什么phpinfo中的xcache.mmap_path值与配置文件中设置的值不同？

xcache.var_size为0或太小而无法启用var数据缓存
