最近Stack Overflow上有一群讨厌perl的人，所以我想我应该把我的“关于你最喜欢的语言你讨厌的五件事”的问题带到Stack Overflow上。拿你最喜欢的语言来说，告诉我你讨厌它的五件事。这些可能只是让你烦恼的事情，承认的设计缺陷，公认的性能问题，或任何其他类别。你只需要讨厌它，它必须是你最喜欢的语言。
不要拿它和其他语言比较，也不要谈论你已经讨厌的语言。不要用你最喜欢的语言谈论你喜欢的事情。我只是想听到你讨厌但能容忍的东西，这样你就可以使用所有其他的东西，我想听到你希望别人使用的语言。
每当有人试图把他们最喜欢的语言强加给我时，我就会问这个问题，有时是面试问题。如果有人找不出他最喜欢的工具的5个缺点，那他对它还不够了解，不能提倡它，也不能利用它赚大钱。他还没有在足够多的不同情况下使用它来充分探索它。他把它作为一种文化或宗教来倡导，这意味着如果我不选择他最喜欢的技术，我就错了。
我不在乎你用什么语言。不想使用特定的语言?那就不要。你通过尽职调查做出了明智的选择，但仍然没有使用它?好吧。有时正确的答案是“你有一个强大的编程团队，有良好的实践和丰富的Bar经验。改成Foo是愚蠢的。”
This is a good question for code reviews too. People who really know a codebase will have all sorts of suggestions for it, and those who don't know it so well have non-specific complaints. I ask things like "If you could start over on this project, what would you do differently?" In this fantasy land, users and programmers get to complain about anything and everything they don't like. "I want a better interface", "I want to separate the model from the view", "I'd use this module instead of this other one", "I'd rename this set of methods", or whatever they really don't like about the current situation. That's how I get a handle on how much a particular developer knows about the codebase. It's also a clue about how much of the programmer's ego is tied up in what he's telling me.
憎恨并不是衡量人们了解多少的唯一尺度，但我发现它是一个相当不错的尺度。他们讨厌的事情也让我知道他们对这个话题的思考有多好。
我偶尔会用我喜欢的PHP，而Python会用得太多。
No namespace; everything is in a
kind of very big namespace which is
hell in bigger environments
Lack of standards when it comes to
functions: array functions take a
needle as a first argument, haystack
as second (see array_search).
String functions often take the
haystack first, needle second (see
strpos). Other functions just
use different naming schemes:
bin2hex, strtolower,
cal_to_jd
Some functions have weird return
values, out of what is normal: This
forces you to have a third variable
declared out of nowhere while PHP
could efficiently interpret an empty
array as false with its type
juggling. There are near no other
functions doing the same.
$var = preg_match_all('/regexp/', $str, $ret);
echo $var; //outputs the number of matches
print_r($ret); //outputs the matches as an array
The language (until PHP6) does its
best to respect a near-retarded
backward compatibility, making it
carry bad practices and functions
around when not needed (see
mysql_escape_string vs.
mysql_real_escape_string).
The language evolved from a
templating language to a
full-backend one. This means anybody
can output anything when they want,
and it gets abused. You end up with
template engines for a templating
language...
It sucks at importing files. You
have 4 different ways to do it
(include, include_once, require,
require_once), they are all slow,
very slow. In fact the whole
language is slow. At least, pretty
slower than python (even with a
framework) and RoR from what I
gather.
不过，我仍然喜欢PHP。这是网页开发的电锯:你想要一个小型到中型网站的速度非常快，并确保任何人都可以托管它(尽管配置可能不同)?PHP就在那里，它无处不在，只需要5分钟就可以安装一个完整的LAMP或WAMP堆栈。好吧，我现在要回去用Python工作了……
