我只是在想什么会给我更好的性能和内存使用.我正在编写一个游戏地图.一切都存储在“地图”类中,但地图可能有数千个图块.现在我在想什么是更好的解决方案：
>将每个tile参数保存在x-y数组中(tile x = 10,y = 11数据存储在数组中,如map [10] [11] = params)如果我想知道某个tile的某些内容,则调用带有x-y参数的不同数组
>将tile视为对象并制作方法,它可以轻松返回tile的邻居,并且所有数据也作为数组存储在每个对象中.
因为我可能有数千个类似的瓷砖,第一印象是它最适合oop编程,但我担心成千上万的对象图块可能会使用更多的内存并且调用它的方法可能会更慢.你怎么看待这件事？

解决方法:
这取决于您使用的PHP版本.如果您使用的版本是PHP5或更高版本(您应该将最新的PHP版本视为游戏应用程序的更高性能),那么使用数组和对象将为您的应用程序提供几乎相同的性能.因此,如果您正在使用/可以使用PHP 5或更高版本,那么您可以根据自己的方便使用数组或对象.
检查此数组与对象比较/测试由Aron Novak：http://aggregation.novaak.net/?q=node/227.
我在Aron Novaks的话中引用它：
I created a small script to find out which data structure has better performance. You can find the script what I used for the test at the attachments.
My test results are:
data structure PHP4 PHP5
object 61.6224 37.576
array 57.6644 37.866
The results are in milliseconds(ms). It seems that in PHP5 the data structure is totally indifferent, in PHP4 there is approximately 7% performance gain if use arrays instead of objects.
"This revolution, however, left PHP's object model mostly unchanged from version 3 – it was still very simple. Objects were still very much syntactic sugar for associative arrays, and didn't offer users too many features on top of that." (http://devzone.zend.com/node/view/id/1717)
So the syntactic sugar is not a bad thing at all :) And it costs almost nothing. This is an explanation why all the parsers' output uses objects.
