使 APC 转储缓存文件的二进制操作码失败？

Question

main.php:

require "/root/test.php";
print_r(apc_cache_info());
apc_bin_dump(array("/root/test.php"));

test.php:

$x = "a";
echo $x;

test.php 执行成功，回显“a”。

apc_cache_info() 显示两个文件都已缓存：

[...]
 [cache_list] => Array
        (
            [0] => Array
                (
                    [type] => file
                    [device] => 2049
                    [inode] => 26472
                    [filename] => /root/test.php
                    [num_hits] => 0
                    [mtime] => 1322736219
                    [creation_time] => 1322737193
                    [deletion_time] => 0
                    [access_time] => 1322737193
                    [ref_count] => 0
                    [mem_size] => 4168
                )

            [1] => Array
                (
                    [type] => file
                    [device] => 2049
                    [inode] => 26476
                    [filename] => /root/main.php
                    [num_hits] => 0
                    [mtime] => 1322736869
                    [creation_time] => 1322737193
                    [deletion_time] => 0
                    [access_time] => 1322737193
                    [ref_count] => 0
                    [mem_size] => 4168
                )

        )
[...]

但是带有 apc_bin_dump 的行会产生一个“神秘”的警告：

    :PHP Warning:  apc_bin_dump(): Excluding some files from apc_bin_dump[file].  Cached files must be included using full path with apc.stat=0. in /root/main.php on line 5
PHP Stack trace:
PHP   1. {main}() /root/main.php:0
PHP   2. apc_bin_dump() /root/main.php:5
PHP Warning:  apc_bin_dump(): Excluding some files from apc_bin_dump[file].  Cached files must be included using full path with apc.stat=0. in /root/main.php on line 5
PHP Stack trace:

PHP   2. apc_bin_dump() /root/main.php:5

怎么了？

Answer 1

它写在消息本身中

必须使用 apc.stat=0 的完整路径包含缓存文件

你的设置是

apc.stat => On => On

禁用apc.stat 或不使用apc_bin_dump()。该消息告诉您，两者都不可能同时进行（无论出于何种原因）。
