这是一个独立工作的脚本，但是当我一起使用它时，它不能正常工作。这里的问题是if条件内部while循环应该从数据库获取值并执行语句取决于$ watch的值的条件，这将在$ rajat中进一步使用。但是while循环只运行了一次。如果我运行while循环和if语句分开，那么它们正在工作。这可能是什么问题。提前感谢您的帮助......

你有一个额外的大括号......

$p_own_con = $row["country"];
$p_own_avt = $row["avatar"];
//} <-- this shouldn't be here
//Check for watchlist
$sql = "SELECT id FROM watchlist WHERE user_id='$y' AND project_id='$pid'";
$query = mysqli_query($db_conx, $sql);
$watch_check = mysqli_num_rows($query);
