推荐答案

每次调用它时，都会分配该变量以告诉您op是否仍在运行:

Every time you call it, that variable is assigned to tell you whether the op is still running:

curl_multi_exec($ch, $running);

此后，如果操作仍在运行，则 $ running 不为零.如果是这样，您将不得不再次调用它(通常是在循环中).

After that, $running is non-zero if the operations are still running. If so, you will have to call it again (normally in a loop).
