PHP调用C#开发的dll类库方法,
PHP调用C#开发的dll类库方法,
有的时候,我们需要在php中利用到其他语言编写的dll类库,如C#编写的dll,方法就是利用PHP new COM方法来调用,在调用之前先要把dll库注册并把程序集放入到全局缓存中。
1. 创建一个 C# Class Library ,命名为:HelloWorld
2. 打开项目的属性,在点选左边的 "Application"(就是第一个tab) , 然后点击Assembly Information 按钮 ,在弹出的Dialog中, 必须在底部勾上: Make assembly COM-visible !否则 , 这个dll将不能以COM方式访问 .( 也可以在代码中的类声明中写上[ComVisible(true)] , 效果一样,需要增加using System.Runtime.InteropServices;引用)
3. 创建强命名签名文件并使用
使用vs.net的“Vsitual Studio .Net工具”-->Vistual Studio .Net命令提示符,输入 sn -k d:\HelloWorld.snk 回车即创建了强命名签名文件
打开项目的属性,点选左边Signing 勾上Sign the assembly 在 Choose a strong name key file:处选择
4. 创建类库并编译成dll
复制代码 代码如下:
namespace HelloWorld
{
//[ComVisible(true)] //or check "Assembly COM-Visible" at Application-Assembly_Information dialog ;
public class Hello
{
public string Write()
{
return "Hello World";
}
}
}
5. 找到dll文件夹路径 ,然后使用vs.net的“Vsitual Studio .Net工具”-->Vistual Studio .Net命令提示符
进入该dll文件夹下输入:
复制代码 代码如下:
regasm HelloWorld.dll
这时候,这个.dll的.net程序集就变成一个标准的Com组件了,但是还不能用,必须让它变成全局Com组件.
将程序集添加到全局程序集缓存中
进入提示符窗口,输入:
复制代码 代码如下:
gacutil /I HelloWorld.dll
这时,你的这个dll就被复制到全局程序集缓存中了.也就是说无论在这个电脑的哪个硬盘上都可以使用此dll组件了.
如果不进行强命名签名,这一步会提示加载失败
PHP测试:
复制代码 代码如下:
$r=new Com("HelloWorld.Hello");
$s=$r->Write();
echo $s;
?>
命令符下:
复制代码 代码如下:
CD [/D] [drive:][path] #进入指定路径
CD [..] #返回父目录
我这里给你一个PHP如何执行系统命令的几个函数,希望能给你带来帮助,我是以Linux举例的,和DOS 的是一样的函数,不过,一定要有执行的权限才可以。 php
php到是可以两、三句代码搞定,你确定你c语言会发布webservices,并且生成标准的soap文件,如果你认为php是c语言写的就可以相互简单调用的话,那你就错了,想法是好的,想结合各自的优点,另外你那点计算,php不能满足,你确定?

A string is a sequence of characters, including letters, numbers, and symbols. This tutorial will learn how to calculate the number of vowels in a given string in PHP using different methods. The vowels in English are a, e, i, o, u, and they can be uppercase or lowercase. What is a vowel? Vowels are alphabetic characters that represent a specific pronunciation. There are five vowels in English, including uppercase and lowercase: a, e, i, o, u Example 1 Input: String = "Tutorialspoint" Output: 6 explain The vowels in the string "Tutorialspoint" are u, o, i, a, o, i. There are 6 yuan in total

JWT is an open standard based on JSON, used to securely transmit information between parties, mainly for identity authentication and information exchange. 1. JWT consists of three parts: Header, Payload and Signature. 2. The working principle of JWT includes three steps: generating JWT, verifying JWT and parsing Payload. 3. When using JWT for authentication in PHP, JWT can be generated and verified, and user role and permission information can be included in advanced usage. 4. Common errors include signature verification failure, token expiration, and payload oversized. Debugging skills include using debugging tools and logging. 5. Performance optimization and best practices include using appropriate signature algorithms, setting validity periods reasonably,

Static binding (static::) implements late static binding (LSB) in PHP, allowing calling classes to be referenced in static contexts rather than defining classes. 1) The parsing process is performed at runtime, 2) Look up the call class in the inheritance relationship, 3) It may bring performance overhead.

What are the magic methods of PHP? PHP's magic methods include: 1.\_\_construct, used to initialize objects; 2.\_\_destruct, used to clean up resources; 3.\_\_call, handle non-existent method calls; 4.\_\_get, implement dynamic attribute access; 5.\_\_set, implement dynamic attribute settings. These methods are automatically called in certain situations, improving code flexibility and efficiency.
