因为 PHP 认为您正在检查字符串“test”的“something”位置。请记住,字符串是字符数组。尝试回显 $array['a']['b']['c']['something']。

::编辑::

我解释了它,我并没有说它有道理。 :P

Because PHP thinks you are checking the 'something'th place of the string 'test'. Remember, strings are arrays of characters. try to echo $array['a']['b']['c']['something'].

::EDIT::

I Explained it, I didn't say it made sense. :P

数组:第四维,isset 返回不可靠

由于您没有对数字进行任何数学运算(因为它只是一个唯一的键),为什么不将其存储为字符串。

$someID = "124234454288758";

另外,值得一提的是,像这样的 SQL 查询创建通常会对 SQL 注入开放。您可能应该考虑使用 PDO,它是 prepare 功能。

Since your not doing any math with the number (since it's just a unique key), why not just store it as a string.

$someID = "124234454288758";

Also, it's worth mentioning that SQL query creation like that is often open to SQL injection. You should probably consider using PDO and it's prepare functionality.

PHP字符串转换时如何保留long int?

C++ Builder(和 Delphi)使用 OMF 格式的 obj 文件。有关详细信息,请参阅此维基百科链接

其他信息: Microsoft Visual C++ 使用不兼容的 COFF,这就是为什么C++ Builder 有一个实用程序来转换它们。

另请参阅: 之间有什么区别OMF 和 COFF 格式?

C++ Builder (and Delphi) use OMF format obj files. See this wikipedia link for details.

Additional information: Microsoft Visual C++ use an incompatible COFF, that's why C++ Builder have a utility to convert them.

See also: What's the difference between the OMF and COFF format?

OBJ文件的内容是什么?

您可以在 Eclipse 中通过多种方式执行此操作

首先打开 Eclipse 并执行以下操作

File->Dynamic Web Project->NewWebProject

将上一个项目的内容复制到 NewWebProject 文件夹中,然后右键单击“New Web Project”

Properties->Project Facets 

并检查是否选中了动态 Web 模块

You can do this several ways in eclipse

Firstly open eclipse and do the following

File->Dynamic Web Project->NewWebProject

copy the contents of the pervious project into the NewWebProject folder then right click on New Web Project

Properties->Project Facets 

and check if dynamic web module is checked

无法将 JSP 项目作为动态 Web 项目导入到 Eclipse 中

您可以尝试在发布的数据中使用单引号而不是双引号

You could try to use single quotes in the posted data rather than double

PHP 有没有自动转义双引号的配置?

是的...只要你这样设计它就可以工作:

input[type="submit"], button, .button, a.actionlink {
    cursor: pointer;
    display: inline-block;
    font-family: "Arial","Verdana","Helvetica","sans-serif";
    font-size: 12px;
    font-weight: bold;
    min-width: 85px;
    -moz-outline: 0 none;
    outline: 0 none;
    padding-bottom: 7px;
    padding-top: 7px;
    text-align: center;
}

Yes... it does work provided you style it this way:

input[type="submit"], button, .button, a.actionlink {
    cursor: pointer;
    display: inline-block;
    font-family: "Arial","Verdana","Helvetica","sans-serif";
    font-size: 12px;
    font-weight: bold;
    min-width: 85px;
    -moz-outline: 0 none;
    outline: 0 none;
    padding-bottom: 7px;
    padding-top: 7px;
    text-align: center;
}

`min-width` 不适用于表单 `input[type="button"]` 元素吗?

501 错误是因为您使用的服务器(大概是 simpleHTTPServer 之类的服务器)不支持 POST 请求。

要解决该错误,您需要使用支持 POST 请求的服务器,例如 apache

The 501 error is because the server you are using (presumably something like simpleHTTPServer) doesn't support POST requests.

To resolve that error you need to use a server that supports POST requests like apache

jQuery ajax post 返回 501 错误代码

如果您想在托管 C++ 实现上运行程序,则需要一个 main 函数。这就是事物的定义方式。当然,如果您愿意,也可以将其留空。在技​​术方面,链接器想要解析运行时库中使用的 main 符号(它不知道您省略它的特殊意图 - 它只是仍然发出对它的调用) 。如果标准指定 main 是可选的,那么实现当然可以提出解决方案,但这需要在平行宇宙中发生。

如果您选择“执行在我的全局对象的构造函数中开始”,请注意您会给自己带来许多与不同翻译单元中定义的命名空间范围对象的构造顺序相关的问题(那么是什么 入口点?答案是:你将有多个入口点,并且首先执行哪个入口点是未指定的!)。在 C++03 中,您甚至不能保证 cout 被正确构造(在 C++0x 中,您可以保证在任何代码尝试使用它之前,只要有前面包含 )。

如果您正确地开始在 ::main 中执行操作,那么您就不会遇到这些问题,也不需要解决它们(这可能非常棘手)。


正如评论中提到的,有一些系统通过让用户告诉在 main 中实例化的类的名称来向用户隐藏 main代码>.其工作原理类似于以下示例

class MyApp {
public:
  MyApp(std::vector<std::string> const& argv);

  int run() {
      /* code comes here */
      return 0;
  };
};

IMPLEMENT_APP(MyApp);

对于该系统的用户来说,完全隐藏了 main 函数,但该宏实际上会定义这样一个主函数,如下所示

#define IMPLEMENT_APP(AppClass) \
  int main(int argc, char **argv) { \
    AppClass m(std::vector<std::string>(argv, argv + argc)); \
    return m.run(); \
  }

这没有问题上述未指定的构建顺序。它们的好处是它们可以与不同形式的更高级别入口点一起工作。例如,Windows GUI 程序在 WinMain 函数中启动 - IMPLMENT_APP 然后可以在该平台上定义这样的函数。

If you want to run your program on a hosted C++ implementation, you need a main function. That's just how things are defined. You can leave it empty if you want of course. On the technical side of things, the linker wants to resolve the main symbol that's used in the runtime library (which has no clue of your special intentions to omit it - it just still emits a call to it). If the Standard specified that main is optional, then of course implementations could come up with solutions, but that would need to happen in a parallel universe.

If you go with the "Execution starts in the constructor of my global object", beware that you set yourself up to many problems related to the order of constructions of namespace scope objects defined in different translation units (So what is the entry point? The answer is: You will have multiple entry points, and what entry point is executed first is unspecified!). In C++03 you aren't even guaranteed that cout is properly constructed (in C++0x you have a guarantee that it is, before any code tries to use it, as long as there is a preceeding include of <iostream>).

You don't have those problems and don't need to work around them (wich can be very tricky) if you properly start executing things in ::main.


As mentioned in the comments, there are however several systems that hide main from the user by having him tell the name of a class which is instantiated within main. This works similar to the following example

class MyApp {
public:
  MyApp(std::vector<std::string> const& argv);

  int run() {
      /* code comes here */
      return 0;
  };
};

IMPLEMENT_APP(MyApp);

To the user of this system, it's completely hidden that there is a main function, but that macro would actually define such a main function as follows

#define IMPLEMENT_APP(AppClass) \
  int main(int argc, char **argv) { \
    AppClass m(std::vector<std::string>(argv, argv + argc)); \
    return m.run(); \
  }

This doesn't have the problem of unspecified order of construction mentioned above. The benefit of them is that they work with different forms of higher level entry points. For example, Windows GUI programs start up in a WinMain function - IMPLEMENT_APP could then define such a function instead on that platform.

你真的需要 C++ 中的 main() 吗?

php base64_encode 功能返回一个字符串。所以 nusoap 正在正确读取类型。尝试先引用内容而不对其进行编码。

$args[]=array('name'=>'content', 'value'=>$content, 'type'=>'Base64Binary');

C.

The php base64_encode functionality returns a string. So nusoap is reading the type correctly. try referencing the content without encoding it first.

$args[]=array('name'=>'content', 'value'=>$content, 'type'=>'Base64Binary');

C.

在nusoap中传递base64Binary类型

我猜我只是愚蠢

我的 load_class() 函数没有正确加载类
我忘记配置我的配置文件并将基本 uri 设置为当前文件夹哈哈
也许我应该删除这个。哦愚蠢 /facepalm

抱歉打扰大家了 xD

guess im just stupid

my load_class() function does not load the class properly
i forgot to configure my Configuration file and set the base uri to the current folder lol
maybe i should delete this one. oh stupidity /facepalm

sorry for bothering everyone xD

@Jullin:当您通过按 F5 从 Visual Studio 编辑器运行项目时,CLR 选择 app.config 文件来读取数据,但是当您想从 .exe (bin/debug 或 bin/release)运行项目时,则 clr 读取 applicationName.exe。 config,您必须在调试或发布或访问 applicationName.exe 的任何文件夹中拥有该文件。

就像我有一个名为“WindowsFormApplication”的窗口应用程序,当我在发布文件夹中成功构建它时,我有 WindowsFormApplication.exe 和 WindowsFormApplication.exe.config 以及其他一些文件。因此,请确保您成功发布项目,并且您的发布文件夹必须包含文件。

@Jullin: When you run project from visual studio editor by pressing F5 then CLR pick app.config file to read data but when you want to run project from .exe (bin/debug or bin/release) then clr read applicationName.exe.config, which you must have within your debug or release or any folder from where you access you applicationName.exe.

Like i have a window application named "WindowsFormApplication", when i build it successfully in release folder i have WindowsFormApplication.exe and WindowsFormApplication.exe.config and some other files. so make sure you release project successfully and your release folder must contain files.

在Release中加载app.config文件

这只是一种预感,但您可能想调查一下它真正尝试序列化的类型 - nHibernate 在运行时为每个 POCO 生成代理(因此它可以执行诸如延迟加载外键实体等操作)。这可能就是您收到此错误的原因。

尝试指定要序列化的确切类型,或者创建一个全新的要序列化的对象,用 nHibernate POCO 的属性填充其属性。

编辑:
这似乎更能解决您的问题:

http://www. west-wind.com/WebLog/posts/147218.aspx

基本上,检查所有 POCO 是否有任何循环引用(例如,具有 Order POCO 作为属性的 Customer POCO,而 Order POCO 具有 Customer's 列表)作为财产)

This is just a hunch but you might like to investigate what type it is really trying to serialize- nHibernate generates proxies for each POCO at runtime (so it can do stuff like lazy loading of foreign key entities, etc.). This may be why you are getting this error.

Try specifying the exact type to be serialized or perhaps create a brand new object to serialize, populating its properties with that of the nHibernate POCO.

EDIT:
This seems to be much more likley the answer to your problems:

http://www.west-wind.com/WebLog/posts/147218.aspx

Basically, check all of your POCO's for any circular references (e.g. a Customer POCO that has an Order POCO as a property while the Order POCO has a list of Customer's as a property)

将 nHibernate 查询序列化为 JSON

实际上,您不需要反转行:

printf -v spaces "%80s" " "; man rev | sed "s/^/$spaces/;s/.*\(.\{80\}\)\$/\1/"

原始:

反转行、填充它们、截断它们并将它们反转回来。

man rev | rev | sed '1{x;s/^$/          /;s/^.*$/&&&&&&&&/;x};G;s/^\(.\{81\}\).*$/\1/;s/\n//' | rev

输出:

这是做同样事情的另一种方法:

printf -v spaces "%80s" " "; man rev | rev | sed "s/\$/$spaces/;s/^\(.\{80\}\).*$/\1/" | rev

Edit:

Actually, you don't need to reverse the lines:

printf -v spaces "%80s" " "; man rev | sed "s/^/$spaces/;s/.*\(.\{80\}\)\$/\1/"

Original:

Reverse the lines, pad them, truncate them and reverse them back.

man rev | rev | sed '1{x;s/^$/          /;s/^.*$/&&&&&&&&/;x};G;s/^\(.\{81\}\).*$/\1/;s/\n//' | rev

Output:

                                          rev — reverse lines of a file or files

                                                                  rev [file ...]

                                                                     DESCRIPTION

Here's another way to do the same thing:

printf -v spaces "%80s" " "; man rev | rev | sed "s/\$/$spaces/;s/^\(.\{80\}\).*$/\1/" | rev
