PHP realizes the function of uploading multiple pictures at one time

I recently encountered a need, which is to upload multiple pictures. Hold down the Ctrl key to select multiple pictures. The image is uploaded once. After the upload is successful, the path and original file name of the image will be saved in the database. This function is generally available in more mature content editor plug-ins. Today I specially selected it to talk about it. I will demonstrate it in the local environment below. A total of three files index.html, conn.php, upload.php

index.html file

<html>
<head>上传文件</head>
<body>
  <form method="post" action="upload.php" enctype="multipart/form-data">
       <input name=&#39;uploads[]&#39; type="file" multiple>
       <input type="submit" name="uploadpic" value="上传">
  </form>
</body>
</html>

Connect to the database conn.php file

<?php
  $conn=mysql_connect("localhost","root","root") or die("数据库服务器连接错误".mysql_error());
  mysql_select_db("test2",$conn) or die("数据库访问错误".mysql_error());
  mysql_query("set character utf8");
  mysql_query("set names utf8");

Image processing upload.php File

<?php
include("conn.php");
$uploadfile; // 图片的名字
if($_POST[&#39;uploadpic&#39;]==&#39;上传&#39;){
  $dest_folder   =  "D:/phpStudy/WWW/picture/";   //上传图片保存的路径 图片放在跟你upload.php同级的picture文件夹里
  $arr=array();   //定义一个数组存放上传图片的名称方便你以后会用的。
  $count=0;
  if(!file_exists($dest_folder)){
      mkdir($dest_folder,700); // 创建文件夹，并给予最高权限
    }
  $tp = array("image/gif","image/pjpeg","image/jpeg","image/png");    //检查上传文件是否在允许上传的类型
  foreach ($_FILES["uploads"]["error"] as $key => $error){
      if(!in_array($_FILES["uploads"]["type"][$key],$tp)){
            echo "<script language=&#39;javascript&#39;>";
            echo "alert(\"文件类型错误!\");";
            echo "</script>";
              exit;
        }
      if($error == UPLOAD_ERR_OK){
        $tmp_name = $_FILES["uploads"]["tmp_name"][$key];
        $a=explode(".",$_FILES["uploads"]["name"][$key]);  //截取文件名跟后缀
          // $prename = substr($a[0],10);   //如果你到底的图片名称不是你所要的你可以用截取字符得到
        $prename = $a[0];
        $name = date(&#39;YmdHis&#39;).mt_rand(100,999).".".$a[1];  // 文件的重命名 （日期+随机数+后缀）
        $uploadfile = $dest_folder.$name;     // 文件的路径
        move_uploaded_file($tmp_name, $uploadfile);
        $arr[$count]=$uploadfile;
        $query="insert into product(name,tupian,pLike) values(&#39;$prename&#39;,&#39;$uploadfile&#39;,&#39;0&#39;)"; // 插入到数据库
        $res=mysql_query($query);
        if($res)
         echo $prename."chenggong<br/>";
         echo $uploadfile."<br />";
        $count++;
         }
        }
        echo "总共".$count."文件";
