为什么PHP中的内置函数如此随机地命名？ [英] Why are the built in functions in PHP named so randomly?

问题描述

似乎没有真正的模式，函数的命名方式，str_replace，strrpos，strip_tags，stripslashes只是一些。

为什么是这样的情况？

编辑 - 这不是一个巨魔类型的帖子 - 只是我认为每次我使用这种语言！

解决方案

PHP语言已经有了一些有机的变化，所以功能的命名是随意的部分。许多不同的格式被保留用于向后兼容性的原因。

有点离题，但除了功能命名的问题，另一个不幸的副作用有机语言的增长在参数排序中是明显不一致的，例如考虑功能 in_array 和 strstr ：

  bool in_array（mixed $ needle，array $ haystack [，bool $ strict ]）
 
 string strstr（string $ haystack，mixed $ needle [，bool $ before_needle = false]）
  

$ b $有趣的是，PHP似乎在内部符合这些顺序，因为所有的字符串函数似乎都使用 $ haystack，$ needle 而数组函数是另一种方式，但是这可能需要一些习惯用于新的PHP的人。有一个很好的在ExpressionEngine上发布，更详细地谈论这个特别的怪癖，以及一个<一个href =http://bugs.php.net/bug.php?id=37088 =noreferrer>关于PHP错误列表的讨论。

随着语言的成熟，有各种各样的尝试来实现更加僵硬和一致的命名约定 - 从 Zend Framework文档：

函数名必须始终以小写字母开头。当一个函数名称由多个单词组成时，每个新单词的第一个字母必须大写。这通常被称为camelCase格式。

filterInput（）

getElementById（）

PHP还有其他问题要解决

It seems that there is no real pattern to the way functions are named, str_replace, strrpos, strip_tags, stripslashes are just some.

Why is this the case?

EDIT - this wasn't meant as a "troll" type post - just something that I think everytime I use the language!

解决方案

The PHP language has grown somewhat organically, so the naming of functions is haphazard in parts. Many of the different formats are retained for backwards-compatibility reasons.

A slight digression, but in addition to the issues with function naming, another unfortunate side-effect of the organic growth of the language is an apparent inconsistency in argument ordering, e.g. consider the functions in_array and strstr:

bool in_array (mixed $needle, array $haystack [, bool $strict])

string strstr (string $haystack, mixed $needle [, bool $before_needle=false])

Funnily enough, PHP seems to be internally consistent with these orderings in that all string functions seem to use $haystack, $needle while array functions are the other way around, but this can take a bit of getting used to for someone new to PHP. There's a good post on ExpressionEngine talking about this particular quirk in more detail, as well as a discussion on the PHP bugs list.

As the language matures, there are various attempts to implement a more rigid and consistent naming convention - from the Zend Framework Documentation:

Function names must always start with a lowercase letter. When a function name consists of more than one word, the first letter of each new word must be capitalized. This is commonly called "camelCase" formatting.

filterInput()

getElementById()

For a slightly different take, from 20 possible reasons why PHP function names and parameters are weird:

• PHP glues APIs and humans together, and sometimes this gets messy

• PHP functions have been developed under many circumstances, sometimes drunk

• PHP function naming algorithm still remains a secret and cannot be cracked

• PHP chose to give people something fun to complain/blog/laugh about

• PHP has other problems to solve
