PHP calls the dll class library method developed by C#
This article mainly introduces the method of PHP calling the dll class library developed by C#, including a complete and detailed DLL production step and PHP calling method, friends who need it can refer to it
Sometimes, we need to use dll libraries written in other languages in php, such as dlls written in C#. The method is to use the PHP new COM method to call. Before calling, the dll library must be registered and the program Set into the global cache.
1. Create a C# Class Library named: HelloWorld
2. Open the properties of the project, click "Application" on the left (the first tab), and then click the Assembly Information button. In the pop-up Dialog, you must check the bottom box: Make assembly COM-visible! Otherwise, this dll will not be accessible in COM mode. (You can also write [ComVisible(true)] in the class declaration in the code, the effect is the same, you need to add using System.Runtime.InteropServices; reference)
3. Create a strongly named signature file and use
Use vs.net’s “Vsitual Studio .Net Tool” -->Vistual Studio .Net command prompt, enter sn -k d:HelloWorld.snk and press Enter to create a strong named signature file
Open the project properties, click Signing on the left and check Sign the assembly. Select
4. Create a class library and compile it into a dll
Copy the code. The code is as follows:
namespace HelloWorld
{
//[ComVisible(true)] //or check "Assembly COM-Visible" at Application-Assembly_Information dialog ;
public class Hello
{
public string Write()
{
return "Hello World";
}
}
}
5. Find the dll folder path, and then use vs.net’s “Vsitual Studio .Net Tool” -->Vistual Studio .Net Command Prompt
Enter the dll folder and enter:
Copy the code. The code is as follows:
regasm HelloWorld.dll
At this time, the .net assembly of this .dll becomes a standard Com component, but it cannot be used yet. It must be turned into a global Com component.
Add the assembly to the global assembly cache
Enter the prompt window and enter:
Copy the code. The code is as follows:
gacutil /I HelloWorld.dll
At this time, your dll will be copied to the global assembly cache. In other words, this dll component can be used no matter which hard drive is on this computer.
If strong naming signature is not performed, this step will prompt loading failure
PHP test:
Copy the code. The code is as follows:
$r=new Com("HelloWorld.Hello");
$s=$r->Write();
echo $s;
?>
Command prompt:
Copy the code. The code is as follows:
CD [/D] [drive:][path] #Enter the specified path
CD [..] #Return to parent directory
