What should I do if php calls exe and says it cannot call the script?

When PHP calls an exe file, it prompts that the script cannot be called

In the actual development process, PHP will encounter the problem of being unable to call the script when calling the exe file. This is usually due to environment variables, permissions, and parameter transfer. caused by problems. This article discusses these issues and their solutions.

1. Environment variables

When calling the exe file, you need to ensure that the directory path where the exe file is located has been added to the system environment variable. Suppose I have an exe file under the D drive, and the file path is "D:\Folder\test.exe", then I need to add "D:\Folder" to the system environment variable. The specific method is as follows:

1. Open the Control Panel;
2. Select "System and Security", then select "System";
3. Select "Advanced System Settings", then select "Environment Variables";
4. Find "Path" in the system variables, and then select "Edit";
5. In the edit environment variable window, add the path to the folder where the exe file is located to the end of the variable value, and then click "OK";
6 .Close all windows, then reopen the cmd window and run the exe file in the cmd window.

2. Permissions

When calling the exe file, you need to ensure that the current user has the permission to access the exe file. If there is no permission, you need to modify the permissions of the file or folder. The specific method is as follows:

1. Find the exe file or folder, right-click and select "Properties";
2. In the "Properties" window Select "Security";
3. Select "Edit";
4. In the "Select User or Group" window, select the user name to which permissions need to be added;
5. In the "Permissions" window, Check the permissions that need to be added, such as "Read and Execute";
6. After clicking "OK", the current user can access the exe file.

3. Parameter passing

When calling the exe file, parameters need to be passed. You can use php's exec() function to execute exe files.

Method 1: Use the exec() function to pass parameters

$param1 = "hello";
$param2 = "world";
$command = "D:\Folder\test.exe $param1 $param2";
exec($command, $output, $status);
print_r($output);

In the above code, $param1 and $param2 are two parameters, and the $command variable stores the path and parameters of the exce file. The exec() function is used to execute $command and store the output results in the $output array.

Method 2: Use the command line to pass parameters

D:\Folder\test.exe hello world

The above code directly passes two parameters on the command line. If the path and file name of the exe file do not contain spaces, you can use it directly. Method Two.

Summary:

When calling the exe file, you need to ensure that the path of the exe file has been added to the environment variable, the current user has permission to access the exe file, and the parameters are passed correctly. If you find that PHP cannot call the script when calling the exe file, you can troubleshoot and solve the problem according to the above steps.
