Question

if (mysqli_connect_errno()==0)
{ // if successfully connected

  $sent_dt=$_POST['scts'];
  // important: escape string values 
  $txt=mysqli_real_escape_string($con, $_POST['text']);
  $snd=mysqli_real_escape_string($con, $_POST['sender']);

  // creating an sql statement to insert the message into the SMS_IN table
  $sql="INSERT INTO SMS_IN(studentID,lastname,firstname,class) VALUES ('34','Lekan','Balogun','Grade8')";
  // executing the sql statement
  $insert_sms_success = mysqli_query($con,$sql);

  // closing the connection
  mysqli_close($con);
}

拜托，我是php的新手，我从朋友那里得到了我的项目代码。我想在插入我的数据库之前使用空格（例如34 Lekan Balogun Grade8）拆分文本消息。我的表字段是：StudentID，LastName，FirstName，Class等我希望它发布为34作为ID，Lekan作为姓氏，Balogun作为名字，等级8进入课堂。感谢您的期待。

Answer 1

您可以在php中使用explode()功能

$str = '34 Lekan Balogun Grade8';
$arr = explode(' ',$str);
echo '<pre>';
print_r($arr);

Answer 2

您可以使用“explode”功能

分割字符串值

 $textArray = @explode(" ",$txt);

  echo "<pre>";
  print_r($textArray);
  echo "</pre>";

Answer 3

这是您完整的代码 if（mysqli_connect_errno（）== 0） {//如果连接成功

              $sent_dt=$_POST['scts'];
              // important: escape string values 
              $txt=mysqli_real_escape_string($con, $_POST['text']);
              $snd=mysqli_real_escape_string($con, $_POST['sender']);
                $arr = explode(' ',$txt);
                echo '<pre>';
                print_r($arr);
                $StudentID = $arr['0'];
                $LastName  = $arr['1'];
                $FirstName = $arr['2'];
                $Class     = $arr['3']

              // creating an sql statement to insert the message into the SMS_IN table
              $sql="INSERT INTO SMS_IN(sms_text,sender_number,sent_dt) VALUES ('$txt','$snd','$sent_dt')";
              // executing the sql statement
              $insert_sms_success = mysqli_query($con,$sql);

              // closing the connection
              mysqli_close($con);
  }
?>
