如何使用PHP上传多个文件

我不知道如何修改以下代码，以使其通过选择一次上传多个文件。通过以下代码，我可以一次上传一个文件。只是希望通过此代码对其进行修改，不仅我要上传文件，还要在同一页面上显示所有已上传的文件，以供下载和删除。

<html>

<title>Brief upload</title>

<?php

date_default_timezone_set("Asia/Calcutta");

//echo date_default_timezone_get();

<?php

$conn=new PDO('mysql:host=localhost; dbname=deu', 'root', '') or die(mysql_error());

if(isset($_POST['submit'])!=""){

$name=$_FILES['photo']['name'];

$size=$_FILES['photo']['size'];

$type=$_FILES['photo']['type'];

$temp=$_FILES['photo']['tmp_name'];

$date = date('Y-m-d H:i:s');

$caption1=$_POST['caption'];

$link=$_POST['link'];

move_uploaded_file($temp,"files/".$name);

$query=$conn->query("INSERT INTO upload (name,date) VALUES ('$name','$date')");

if($query){

header("location:index.php");

}

else{

die(mysql_error());

}

<html>

<body>

</head>

<?php include('dbcon.php'); ?>

<style>

您可以通过这种方式上传多个文件输入字段必须定义为数组，即 images[]它应该定义为 multiple="multiple"<input name="images[]" type="file" multiple="multiple" />// Count # of uploaded files in array$total = count($_FILES['images']['name']);// Loop through each filefor( $i=0 ; $i < $total ; $i++ ) {  //Get the temp file path  $tmpFilePath = $_FILES['images']['tmp_name'][$i];  //Make sure we have a file path  if ($tmpFilePath != ""){  //Setup our new file path  $newFilePath = "./uploadFiles/" . $_FILES['images']['name'][$i];//Upload the file into the temp dirif(move_uploaded_file($tmpFilePath, $newFilePath)) {  //Handle other code here } }}有关更多详细信息，PHP多次上传
