我不是很熟悉PHP,我有以下代码,允许我上传文件到服务器.我怎样才能上传多个文件,在我的html中我已经添加了多个属性.php代码是这样的:
<?php
session_start();
$allowedExts = array("jpg", "jpeg", "gif", "png");
$extension = end(explode(".", $_FILES["file"]["name"]));
if ((($_FILES["file"]["type"] == "image/gif")
|| ($_FILES["file"]["type"] == "image/jpeg")
|| ($_FILES["file"]["type"] == "image/png")
|| ($_FILES["file"]["type"] == "image/pjpeg"))
&& ($_FILES["file"]["size"] < 20000)
&& in_array($extension, $allowedExts))
{
if ($_FILES["file"]["error"] > 0)
{
echo "Return Code: " . $_FILES["file"]["error"] . "<br />";
}
else
{
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Temp file: " . $_FILES["file"]["tmp_name"] . "<br />";
if (file_exists($_SESSION['user']."/" . $_FILES["file"]["name"]))
{
echo $_FILES["file"]["name"] . " already exists. ";
}
else
{
move_uploaded_file($_FILES["file"]["tmp_name"][$i],
$_SESSION['user']."/" . $_FILES["file"]["name"]);
echo "Stored in: " . $_SESSION['user']."/" . $_FILES["file"]["name"];
}
}
else
{
echo "Invalid file";
}

可以选择多个文件,然后使用
<input type='file' name='file[]' multiple>
执行上传的示例php脚本:
<html>
<title>Upload</title>
<?php
session_start();
$target=$_POST['directory'];
if($target[strlen($target)-1]!='/')
$target=$target.'/';
$count=0;
foreach ($_FILES['file']['name'] as $filename)
{
$temp=$target;
$tmp=$_FILES['file']['tmp_name'][$count];
$count=$count + 1;
$temp=$temp.basename($filename);
move_uploaded_file($tmp,$temp);
$temp='';
$tmp='';
}
header("location:../../views/upload.php");
?>
</html>
所选文件作为数组接收
$_FILES['file']['name'][0]存储第一个文件的名称.
$_FILES['file']['name'][1]存储第二个文件的名称.等等.
