所有命令都在Debian系统上通过CLI执行。
get_loaded_extensions（）列出“apc”，我的 APC-settings for CLI 是：
apc

apc.user_ttl => 0 => 0
apc.write_lock => On => On
清除APC ：
php -r "print_r(apc_clear_cache());"
给出“1”。
执行一个非常简单的PHP文件“test.php”：
php test.php
但现在执行 apc_cache_info （）：
php -r "print_r(apc_cache_info());"
似乎显示没有缓存数据：
Array
(
[num_slots] => 1031
[ttl] => 0
[num_hits] => 0
[num_misses] => 0
[num_inserts] => 0
[expunges] => 0
[start_time] => 1322733678
[mem_size] => 0
[num_entries] => 0
[file_upload_progress] => 1
[memory_type] => mmap
[locking_type] => pthread mutex Locks
[cache_list] => Array

[3] => 0
[4] => 0
[5] => 0
[6] => 0
[7] => 0
[8] => 0
[... ever value is 0 ... ]
为什么会这样？
我想要做的是在CLI上使用APC，缓存文件的操作码，然后“看到”某些内容已被缓存。

好的，似乎CLI正在遭受CLI上的进程间痴呆症。
这意味着运行后续脚本“main.php”：
<?php
apc_clear_cache();
print_r(apc_cache_info());
require "test.php";
print_r(apc_cache_info());
将给出最后一行：
Array

[num_slots] => 1031
[ttl] => 0
[num_hits] => 0
[num_misses] => 1
[num_inserts] => 2
[expunges] => 0

[mem_size] => 4168

CLI脚本会创建一个APC段，该段在脚本末尾被销毁。因此，运行另一个脚本来显示APC信息将创建一个没有数据的新段。
您无法在CLI中使用APC缓存，其内存仅保留在服务器池中（PHP-FPM，Apache + PHP，Lighttpd + FastCGI ...）。例如，这是一个关于如何在cron脚本中设置APC缓存的示例：https://www.dugwood.com/949904-php5-opcode-caching-and-memory-storage-with-apc-xcache-in-command-line-interface-cli-or-cron.html
如果在使用CLI调用的脚本中运行apc_cache_info()，则可以实现查看变量。在大多数情况下，APC在CLI中是无用的，它仅用于调试目的（并且在配置文件中默认为apc.enable_cli）。
