問題描述
我有一個 foreach 循環(huán)，它在其中分叉.在進程 fork 之后，它訪問數(shù)據(jù)庫.我收到一個錯誤:
I have a foreach loop that forks within it. After the process forks, it accesses the database. I get an error:
SQLSTATE[HY000]: General error: 2006 MySQL server has gone away
問題是，我正在分叉之后連接到數(shù)據(jù)庫.
The thing is, I'm connecting to the database after I've forked.
我的問題:為什么會發(fā)生這種情況?
My question: Why would this be happening?
如果發(fā)生這種情況，我是否真的在分叉之前訪問了數(shù)據(jù)庫??孩子會繼承數(shù)據(jù)庫連接嗎?
If this happens, am I actually accessing the database before forking? Will the child inherit DB connections?
(注意:我可以發(fā)布代碼，但它相當(dāng)大，因為它都在類中，這可能是導(dǎo)致我在訪問數(shù)據(jù)庫時感到困惑的原因.您應(yīng)該知道的另一件事是我正在使用 ZF.)
(note: I can post code, but it's rather large as it's all in classes, which could be what is causing my confusion of when I'm accessing the DB. Another thing you should know is I'm using ZF.)

閱讀更多內(nèi)容我看到分叉的孩子確實繼承了他們父母的數(shù)據(jù)庫連接，這是一個已知問題:http://php.net/manual/en/function.pcntl-fork.php#70721
Reading more into it I see forked children do inherit their parent's db connection, and it is a known problem: http://php.net/manual/en/function.pcntl-fork.php#70721
