严格的类型 [英] Strict types
问题描述
大家好，
一段时间以来我一直希望PHP有（至少可以选择
启用）严格类型。这将有助于大量的BIG
应用程序，并且可能开始逐渐减少数百万行的废话
代码。
PHP是一种很棒的语言，但是大量无能的编码器
绝对没有什么可以帮助语言增长。我知道我们都必须从某个地方开始
，所以请不要认为我是精英主义者，因为我不是b $ b，但有些东西需要要做的就是把那些烂摊子搞得一团糟。
当然这里的承包商目睹了这一点，还是仅仅是我？
什么是其他人的意见？
干杯，

Hi All,
For a while now I''ve been wishing PHP had (at least the option to
enable) strict types. It would help a massive amount in BIG
applications, and maybe start to taper the millions of lines of crap
code that''s out there.
PHP is a great language, but the masses of incompetant coders out there
do absolutely nothing to help the language grow. I know we all have to
start somewhere, so please don''t think I''m being eliteist, because I''m
not, but something has to be done to try to fix the mess out there.
Surely the contractors on here have witnessed this, or is it just me?
What is everyone else''s opinion?
Cheers,
T''rog

To说实话，唯一真正的问题是对象。对于大型
应用程序，一致的命名方案有助于简单的变量和
a很多情况下变量不是很重要。
关于对象，PHP5现在有类型提示，确保函数或方法的参数
属于给定类型（类）：
功能栏（Foo
To be honest the only real problem is with objects. For large
applications a consistent naming scheme helps with simple variables and in
a lot of cases it''s not really important what the variable is.
With regards to objects, PHP5 now has type hints which ensures a parameter
to a function or method is of a given type (class):
function bar(Foo
foo）
{
...
}

好吧，你可以通过将所有基本类型包装在类中来实现PHP5中
喜欢java做很多事情。然后每个类型类都有它的
拥有toXXX转换器来处理强制转换。
这是用另一个抽象级别修复的一个例子''而且我想知道这一切的实用性。 PHP - 就像shell一样 - 通常很有吸引力
编码器*因为*它是松散的类型。
我不知道有多少编码器会找到PHP如果他们不得不遵循更严格的对象类型编码，那就很有吸引力。例如：
Well, you could do it in PHP5 by wrapping all the basic types in classes
like java does for a lot of things. Then each type class would have its
own toXXX converters to handle the casts.
This is an example of ''fixed with another level of abstraction'' and I
wonder at the utility of it all. PHP - like shell - is often attractive
to coders *because* it is loosely typed.
I''m not sure how many coders would find PHP as attractive if they had to
follow stricter object type coding. For example:
