宝马娱乐在线PHP中txt导入mysql代码

注意在导入时保持数据库教程的编码与txt文档编码尽量一样，要不可能出现乱码问题哦。

 代码如下

<?php教程
  //验证文件类型和错误
if($_FILES["insert_first"]["type"] == "text/plain"){
    echo "第一步：文件类型上传正确"."<br/>";
        if($_FILES["insert_first"]["error"]){
          echo "上传错误：".$_FILES["insert_first"]["error"]."<br/>";
        }else{
          echo "文件名称:".$_FILES["insert_first"]["name"]."<br/>";
          echo "文件类型:".$_FILES["insert_first"]["type"]."<br/>";
          echo "文件大小:".($_FILES["insert_first"]["size"]/1024)."Kb<br/>";
          echo "临时名称:".$_FILES["insert_first"]["tmp_name"]."<br/>";
        }       
  }else{
    echo "上传文件格式不正确";
        exit;
}

//连接数据库
$con = new mysql教程i('localhost','s503440db0','td9928ps教程','s503440db0');
if(mysqli_connect_errno()){
  echo "链接数据库失败";
  exit;
}
 
 
//打开文件
$file = fopen($_FILES["insert_first"]["tmp_name"],"r") or exit("打开文件失败!");

var_dump($file);
echo "<br/>";

while(!feof($file)){ 
  //逐行分拆
  $row = explode(",",fgets($file));
  $row0 = $row[0];
  $row1 = (string)$row[1];
  echo "$row0"."---"."$row1"."<br/>";

  //判断记录是否存在
        $query1 = "select firstid from firstcategory where firstid=$row0";
        $query2 = "select firstname from firstcategory where firstname='$row1'";
        $result1 = $con->query($query1);
        $result2 = $con->query($query2);
    //判断行数
        $result1 = mysqli_num_rows($result1);
        $result2 = mysqli_num_rows($result2);

                 
    if($result1){
          echo "行号{$row0}已存在<br/>";
        }elseif($result2){
          echo "分类{$row1}已存在<br/>";
        }else{
          $query = "insert into firstcategory (firstid,firstname) values ($row0,'音乐')";
          $result = $con->query($query);
        }
}
echo "导入结束，请检查数据是否正确 http://www.111cn.net ";
