我用php编写了以下函数 mysqli_query 在没有任何错误或异常的情况下运行。然而 INSERT INTO 声明或 $insert 变量似乎没有按预期工作，我也弄不明白。我意识到仅仅发布代码的一部分可能会让我很难确定它为什么不工作，但是我真的希望确认这个函数中没有错误。
我需要利用 mysqli_real_escape_string 对于提供的每个url？我试着改变 $website 至 $_website 但它什么也没回来。
只是想弄清楚是否有什么地方我做错了，妨碍了sql查询的工作。它不返回使调试变得困难的错误。提前谢谢！

$jp = mysqli_connect("localhost", "myuser", "password", "mydatabase");

if (!$jp) {
    echo "Error: Unable to connect to MySQL." . PHP_EOL;
    echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
    echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
    exit;
}

  if (stripos($website, "http://") !== 0)   //doesn't start with http:// ? , then add it
      $website = "http://" . $website; 
  // $_website = mysqli_real_escape_string($jp, $website); // THIS DOESNT RETURN ANYTHING
