How to close PHP after running the program by using $ cmd

How can I close a PHP program when I borrow $ cmd to run it? I want to use PHP to run an exe program (do not use CRON or other scheduler programs, and there is other content in PHP. This is convenient for testing. take notepad as an example). after it is opened for 3 seconds, close it. What should I do? Can I disable it by calling the task manager? Find the solution code. Thank you. PHPcode & lt ;? Php $ cm PHP after running the program using $ cmd, how can I close it?

Popen-open process file pointer

Description
Resource popen (string $ command, string $ mode)
Open an Pipeline pointing to a process, which is generated by running the command derived from a process.

Returns the same file pointer as fopen (), except that it is unidirectional (can only be used for read or write) and must be disabled using pclose. This pointer can be used for fgets (), fgetss (), and fwrite ().

If an error occurs, FALSE is returned.

Note:

If bidirectional support is required, use proc_open ().



Example #1 popen () Example


  $ Handle = popen ("/bin/ls", "r ");
?>

Note:

If the command to be executed is not found, a valid resource is returned. This looks strange, but it makes sense. It allows access to any error message returned by the shell:


  Error_reporting (E_ALL );

/* Add redirection to get stderr output with a standard error. */
$ Handle = popen ('/path/to/spooge 2> & 1', 'r ');
Echo "'$ handle';". gettype ($ handle). "\ n ";
$ Read = fread ($ handle, 2096 );
Echo $ read;
Pclose ($ handle );
?>

   $ Handle = popen ('C: \ WINDOWS \ system32 \ notepad.exe ', "r ");
   
Pclose ($ handle );
   
?>
   

  
------ Solution --------------------
Popenet returns the process pointer of notepad.exe in the php environment. this pointer can only be used to read and output data to notepad. only the pointer of pclose is closed, not the notepad itself.

I do not know how to disable notepad, but I want to find out how to obtain the process in the task manager from the basics of windows programming, and then use the system function to call the program to close windows.

Popen is unidirectional. use proc_open.
Try it

  
  

   
   
PHP code
   
   
/*** Windows only */$ descriptorspec = array (0 => array ("pipe", "r"), 1 => array ("pipe ", "w"); $ cwd = 'C: \ WINDOWS \ system32 '; $ process = proc_open('notepad.exe', $ descriptorspec, $ pipes, $ cwd ); $ s = proc_get_status ($ process); // all the information obtained is the status of the parent node. exe, rather than the child node. notepad.exe. therefore, you cannot kill the process idsleep (3) directly; exec ('taskkill/pid '. $ s ['pid ']. '/t'); // tree deletion: deletes all parent processes and their child processes. I thought that the child process id must be greater than the parent process. I wrote a piece of code and later found that it was not, and found the command proc_close ($ process );
