问题描述
我需要在数据库中存储很多二维数组，并且不确定要使用什么:serialize或implode.因此，我进行了一些测试，以找出哪个工作更快，并得出结论是serialize:
I need to store lots of two-dimensional arrays inside database and was not sure what to use: serialize or implode. So I did a few tests, to find out which one is working faster and came to the conclusion it was serialize:
Execution times: 1'000'000
Serialize: 1.4974119663239 seconds
Implode: 2.5333571434021 seconds
Explode: 4.0185871124268 seconds
Unserialize: 1.6835169792175 seconds
所以问题是:为什么 implode + explode 比 serialize + unserialize 慢得多?
So the question: Why is implode+explode so much slower then serialize+unserialize?

推荐答案
我的想法是explode/implode对字符串进行操作，这就是为什么，而serialize/unserialize则在此位置输出/输入字符串结束/开始. implode中的字符串越多，explode中的字符串越长，它越慢，您是否尝试过?
My idea is that explode/implode operate on strings that's why, while serialize/unserialize output/input a string at the very ending/beginning. Probably the more strings you implode and the longer string you explode, the slower it is, have you tried?
使用哪个我不知道，这取决于您以后是否要处理输出字符串，我认为serialize d字符串更难解析.但是要将其存储在数据库或文件中，我将使用serialize.
Which to use I don't know, it depends if you later wish to handle output string, I think serialized string is more difficult to parse. But to store it in database or file I'd use serialize.
