在php中执行.exe并填充输入

Question

Firstly, sorry for my English. Is it possible to start .exe program with php script and pass input after the program has started. I can't use command line arguments.

#include <iostream>
using namespace std;
int main() {
    int a, b;
    cin>>a>>b;
    return a+b;
}

Answer 1

Use popen or proc_open.

<?php
    $handle = popen('echo 1 2 | /path/to/compiled-program', 'r');
    $read = fread($handle, 32);
    echo $read;
    pclose($handle);
?>

BTW, your c++ program does not compile.

#include <iostream>
using namespace std;

int main()
{   
    int a, b;
    cin >> a >> b;
    cout << a + b << endl;
    return 0;
}
