我无法使用来自单独的PHP脚本"file2"的apc_fetch来访问存储的缓存.

I cannot use apc_fetch from separate PHP script "file2" to access stored cache.

从文件1触发apc_fetch时，它确实起作用.

It does work when trigger apc_fetch from file1.

文件:1_store_variable_in_memory.php

<?php

$token = "my_token_value";
apc_store('token_1', $token);
// var_dump(apc_fetch('token_1')); // Moved to file 2

文件:2_access_memory_stored_variable.php

<?php

var_dump(apc_fetch('token_1'));

文件2的结果

bool(false)

文件2的预期结果

string(14) "my_token_value"

推荐答案

进程结束后，PHP cli中的APC被清除，而且多个php cli进程之间不共享内存.因此，这可能不是您要用来解决问题的工具.

APC in PHP cli gets cleared after process is ended, moreover the memory is not shared between multiple php cli processes; because of it this is probably not the tool you want to use to solve your problem.

如果需要在进程之间保留的缓存，请尝试Redis或memcached.

Try Redis or memcached if you need a cache that is persisted between processes.
