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 code
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:$result
"; } fclose($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 $return_value
";}?>c++代码如下
- C/C++ code
#includeusing namespace std;int main(int argc,char *argv[]){ char buf[1024]={0}; /*fgets(buf,sizeof(buf),stdin);*/ while(buf[0]!='q') { std::cin>>buf; std::cout<
上面的c++是简化的代码
(1)问题是我的c++中代码是个while循环要求持续的输入
问php中应该怎么写，现在的的php中只能fwrite($pipes[0], "q");，其它的就不行
(2)上面那段程序到能正常打印
r:q
command returned -3
我在另一个非常复杂的cpp程序去始终打印如下：
r:
command returned -1073741515
后来我在main中把其他的代码都注释掉直接复复制上面简单的c++代码到我的工程中结果还是上面的，这是我最纳闷的地方，有人遇到过么
求教高人，万分感谢
------解决方案--------------------
fwrite($pipes[0], "cmd1\ncmd2\ncmd3\nq"); 试试看
------解决方案--------------------
啥意思？
他让你将逐次输出的数据组装成串后一次性输出
