问题描述

什么代码会更快（或更好）：

What code will be faster (or better):

$this->db->set('date', 'NOW()', FALSE);

或

$data['date'] = date('Y-m-d H:i:s');

推荐答案

高架。但我不会说PHP中的函数调用非常昂贵，因为 qwertzman回答。 Ok它可能比其他语言慢，但这真的不是重点。查看此比较与1,000,000函数调用。

In general all function calls will be slower because of the overhead. However I won't say function calls in PHP are very expensive as qwertzman answered. Ok it may be slower compared to other languages, but that really isn't the point. Have a look at this comparison with 1,000,000 function calls. You see what you gain?

当谈到哪一段代码更快时（在你的OP中）你在谈论微优化，而且真的是一些您不应该担心< a>。

When talking about which piece of code is faster (in your OP) you're talking about micro-optimization and is really something you shouldn't have to worry about.

真正的问题是哪段代码是：更好的可维护性，可读性，可理解性。

The real question is which piece of code is: better maintainable, readable, understandable.
