我正在使用popen来执行命令，问题是我在脚本执行时只在开始时立即输出（条目在我的数据库中），并且在完成后没有任何意义我。我试图得到它，以便在popen进程工作时，输入不断进入我的数据库。有人有什么想法吗？
$handle = popen ('/usr/local/bin/ffmpeg -i /home/g/Desktop/cave.wmv ' .
'-deinterlace -acodec libfaac -ab 96k -ar 44100 -vcodec libx264 ' .
'-s 480x320 -f flv /home/g/Desktop/file.flv 2>&1', 'r');
if ($handle) {
echo 'after handle if <br>';
while(! feof ($handle)) {
echo 'after handle while <br>';
echo $read = fgets ($handle);
echo 'after read <br>';
$sql = 'INSERT INTO video (timestamp, vid_id, file_name, ' .
'uploader, title, subject_id, status) VALUES(?,?,?,?,?,?,?)';
$stmt3 = $conn->prepare($sql);
echo 'after stmt3 <br>';
$result = $stmt3->execute(array('','',$read,'','untitled','',0))
or die(print_r($db->errorInfo(), true));
print "after execute " . $result . "<br>";
if (!$result) {
echo "\nPDO::errorInfo():\n";
print_r($dbh->errorInfo());
}
}
pclose ($handle);
}
输出为：

答案 0 :(得分：2)
您是否在timestamp列上有唯一约束（例如主键）？由于PHP time()函数为您提供了UNIX时间值（分辨率为1秒），因此不允许您快速连续插入记录 - 它们将具有相同的密钥。
我假设的原因是因为你既没有检查execute的返回值来检测失败，也没有在失败的情况下调用errorInfo。
即使该唯一约束不是问题，您也应该检查返回值和错误信息。这应该告诉你完全问题是什么。
要尝试的另一件事是在每个行之后临时放置调试print语句，以跟踪代码中的流程。
