php中的proc_open+fwrite应用问题
我想在php用proc_open调用一个c++写的exe程序，由于里面有要求输入参数所以我用fwrite写入终端，php代码如下
<?php$descriptorspec = array( 0 => array("pipe", "r"), // stdin is a pipe that the child will read from 1 => array("pipe", "w"), // stdout is a pipe that the child will write to 2 => array("file", "error-output.txt", "a") // stderr is a file to write to);$process = proc_open("d:\\64test.exe", $descriptorspec, $pipes);if (is_resource($process)) { // $pipes now looks like this: // 0 => writeable handle connected to child stdin // 1 => readable handle connected to child stdout // Any error output will be appended to /tmp/error-output.txt fwrite($pipes[0], "q"); fclose($pipes[0]); while (!feof($pipes[1])) { $result = fgets($pipes[1], 1024); echo "r:$result<br>"; } fclose($pipes[1]); // It is important that you close any pipes before calling // proc_close in order to avoid a deadlock $return_value = proc_close ($process); echo "command returned $return_value<br>";}?>#include <iostream>using namespace std;int main(int argc,char *argv[]){ char buf[1024]={0}; /*fgets(buf,sizeof(buf),stdin);*/ while(buf[0]!='q') { std::cin>>buf; std::cout<<buf; } return -3;}
