blocks|key|1135557|text|是的，使用OOP几乎总是一个好主意。这是因为OOP是一种编码风格，而编码风格在很大程度上很容易在跨语言之间传递。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1135558|人们不使用编码风格，因为他们使用一种特定的语言。人们使用编码风格是因为编码风格提供了很好的方法来做他们想要的事情。因此，只要有基本元素(继承、类属性等)，就可以用这种编码风格编写代码。|1135559|不，使用过程函数来访问它们可能不是一个好主意。这是因为，您可能必须执行类似的操作来维护状态。|1135560|function+myFunc()

Yes, it is almost always a good idea to use OOP. This is because OOP is a style of coding, and coding styles for the most part are easily able to be transferred accross languages. 

People don't use coding-styles because they use a certain language. People use coding styles because the style of coding offers good methods to do things they feel are desirable. Therefore, as long as the basic elements are there (inheritance, class properties, etc), it will always be viable to write in that coding style.

No, using procedural functions to access them probably isn't a good idea. This is because, you probably will have to do something like this to maintain the state.

<pre><code>function myFunc()
{
 global $class;
 $class-&gt;doMethod();
}

function myFunc2()
{
 global $class;
 $class-&gt;doMethod2();
}
</code></pre>

This is a bad idea as it creates a ton of global state.

blocks|key|1135581|text|如果您担心在PHP中使用OO的原因是速度，请不要担心:+PHP是一种到处都很慢的语言。如果您正在做的事情是处理器密集型的，那么您根本就不应该使用PHP。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1135582|关于静态函数，这是一个设计选择，但我在避免完全由静态函数组成的类方面犯了错误。与前缀相比，它真的没有什么优势，仅仅因为它不是一个好主意就使用一个结构。|1135583|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

If the reason you're worried about using OO with PHP is speed, fear not: PHP is a slow language all around. If you're doing something that's processor-intensive enough for the speed loss from using objects to matter, you shouldn't be using PHP at all.

With regards to static functions, this is a design choice, but I'd err on the side of avoiding classes made up entirely of static functions. There's really no advantage to it over prefixes, and using a construct just because it's there isn't a good idea.

I was curious of this myself. Unfortunately after I changed my code from procedural to oop I ran some benchmarks and not beforehand.

Here's the benchmark code.

<pre><code>class game{
 function maxp($val){
 return max(0,pow($val,0.5)); 
 }
}

$game = new game;

for($i=0;$i&lt;100000;$i++){
 $game-&gt;maxp(100);
 //game::maxp(100);
}
</code></pre>

OOP results ranged between 0.13 and 0.2 seconds;

Procedural results ranged between 0.08 and 0.1 seconds.

The results remained consistent over a good length of time.

I encourage you to run your own tests.

php 5.4.3

There are many debates on whether Object Oriented Programming is good or not. But, using OOP in Php is slower. Would it be a good trade to use procedural programming and faster speed and OOP with slower speed (since classes have to be initiated every time a page loads and big websites will start to become slow).

More importantly, would it be good to wrap stuff inside a class and use static functions or would it be better to just have many lying functions with a prefix ex: wp_function().

Is OOP worth using in PHP?

在面向对象编程是否好的问题上有很多争论。但是，在Php中使用OOP要慢一些。使用过程化编程和较快的速度以及较慢的OOP速度(因为每次页面加载时都必须启动类，而大型网站将开始变得缓慢)，这是一种很好的交易吗？更重要的是，在类中包装东西并使用静态函数是好的，还是只有许多带有前缀ex: wp_function()的躺着的函数...
