PHP的mysql_fetch_row是从执行的SQL查询中检索数据的唯一方法。

老实说，我编写了一个完整的web应用程序，而没有使用mysql_fetch_array，并且每次我想要更改函数以添加额外的列时都必须更改一堆数字。

我一直认为，任何为任何语言编写任何代码的人都会使用编辑程序。

I was working with a client of mine who had me on mostly as support and to write some of the more complex things for him. Well one day he messed up a file, big time. He accidentally saved over three hours worth of his own work, and when I asked him why he didn't save more often he replied with, "because I wasn't done". Naturally, this was not an acceptable answer, and I poked and prodded a little further. I eventually came to find out that he he has never used any editing program, EVER! Not even notepad.exe! He had been using an online CPanel editor for files! It didn't even have a 'Find' function. He couldn't ever save until he was done because he was editing the live file on the site!

不用说，我很惊讶，他至今仍在使用CPanel编辑器……

640K应该足够任何人(DOS)。多年来，很多人都相信这一点。

当我第一次拥有8MB内存的系统时，我认为这远远超过了我的需求。它可以运行操作系统(Mac)以及我使用的所有应用程序(Word、Email、Firefox等)。

我可能花了几天时间试图减少业务层使用的内存，后来才意识到项目的WinForms (GUI)使用的内存是应用程序其他部分的4倍多。

如果每一行都计算条件，如果你写这样的代码:

Dim a as Boolean = True
If a Then
    Console.WriteLine("1")
    a = False
    Console.WriteLine("2")
Else
    Console.WriteLine("3")
End If

那么输出将是:

1
3

当我在TI-83上编程时，我认为你不能给变量赋值。因此(忽略这是C代码，不是TI-BASIC)而不是编写

c = c + 1;

我会写

d = c + 1;
c = d;

当我学习+=和++时，我惊呆了。
