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……

我对特尔斐的5分:

Procedures and functions aren't necessarily distinguished from variables if not parameterized (eg, I can have statement such as x := GetPositionOnScreen; instead of x := GetPositionOnScreen();) Try/Finally and Try/Except needs to be nested (stated once before, but it's still one of mine as well). Not case sensitive. Can have a multiple objects (functions, global variables, local variables) named the same and Delphi will happily try to figure out what you mean. names should be unique. Odd if condition rules. a single conditional check doesn't require a () around it, but if I do multiple checks, I need a () around each one, and sometimes multiple nested sets for bigger checks. No inherited includes. If I need to reference functionality from the Windows unit in a base and an inherited form, I have to include Windows in both.

VB。网

The behavior AndAlso / OrElse and And / Or seems backwards. Perhaps they should be switched. When can only be used for exception catching. The ability to do a When conditional would be nice for some other things. There is no friggin Refactoring in the VS IDE (not really the language's fault) like there is with C# Not <obj> Is Nothing. Yes, this has been remedied by IsNot, but for some reason I see the Not Is being used too often. (I see it much more frequently with devs who speak english as a second language, does it make better sense from that angle?) It doesn't require the () on ToString() and most functions. (Leads to sloppy coding habits) Having to do _ when breaking a line. It allows optional parameters. (Leads to sloppy coding habits) declaring an array is done by UpperBound and not by capacity. "Dim arr(2) as String" will actually hold 3 elements. Having = be a comparison and assignment operator.

JavaScript

Function object syntax: f = new Function( "foo", "bar", "return foo+bar;" ); (It takes n arguments, the first n-1 are arguments for the function, then nth is the actual function, in string form. Which is just silly.) Function arguments can be repeated. f = new Function( "foo", "foo", "return foo;" ); The last repetition is the only one ever used, though: f( "bye", "hi" ) // returns "hi" f( "hi" ) // returns undefined E4X should just die. My users are always complaining that it doesn't work the way they think it will. Let's face it, when you need a page and a half of psuedocode for a setter, it's time to rethink things. A standard notion of stdin/stdout/stderr (and files!) would be nice. null != undefined It's irritating to have to handle them both. Sometimes it's useful, but most languages manage to limp along fine with one.

C++

The inconsistencies in the libraries related to char* and std::string. All C++ libs should take std::strings. Characters are not bytes with respect to iostream. I do a lot of byte-oriented work. Having a "byte" type and a "character" type would significantly make it simpler. That, too, would permit scaling to Unicode somewhat easier. Bit operations should be easy on a value. I should be able to access and set the n'th bit of a value without playing AND/OR dancing. The lack of a standardized interface for GUIs. This is where Microsoft has really been able to position themselves well with C#. A standard interface binding that OS makers provide would go really far for my work.

我是在冒险，因为我不能全职使用它，但无论如何我会尝试一下!

Perl 6

func("frew") != func ("frew") It annoys me, but there is good reason for it. In Perl 5 print (5 + 6) * 10 still gets me every now and then It may be easier to parse than Perl 5 in a lot of places, but it still kills my editor sometimes It still has a lot of the line noise Perl 5 which scares a lot of people. That means it's harder to get them excited etc. There are no libraries yet. This will be a non issue if Perl 6 does indeed end up supporting Perl 5, but that may be a burden not worth bearing. There's no REPL, or what rubyists would call irb. A solid interactive Perl 6 with tab completion, color coding, etc, would make using and learning it so much nicer. Currently the documentation is basically the English spec. Not exactly an easy read. I know it's a stupid cliche, but it's not out yet! (I am allowed to complain because I am helping :-P)

前三点是语言;剩下的并不是语言本身，而是它还没有问世的事实。
