问题是当用户关闭浏览器时,inotifywait进程保持打开状态,依此类推.

有什么方法可以避免这种情况吗？

<?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("pipe","a") // stderr is a file to write to
);

$PRocess = proc_open('inotifywait -mc -e create /dev/shm/test/',$descriptorspec,$pipes);

if (is_resource($process)) {

  header("Content-type: text/htML;charset=utf-8;");
  ob_end_flush(); //ends the automatic ob started by PHP
  while ($s = fgets($pipes[1])) {
    print $s;
    flush();
  }
  fclose($pipes[1]);
  fclose($pipes[0]);
  fclose($pipes[2]);

  // 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\n";
}
?>
