<?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 $return_value<br>";
}
?>
c++代码如下
#include <iostream>
using namespace std;
int main(int argc,char *argv[])
{
char buf[1024]={0};
/*fgets(buf,sizeof(buf),stdin);*/
while(buf[0]!='q')
{
std::cin>>buf;
std::cout<<buf;
}
return -3;
}
上面的c++是简化的代码
(1)问题是我的c++中代码是个while循环要求持续的输入
问php中应该怎么写，现在的的php中只能fwrite($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
