[PHP实例] PHP多文件上传实现

来源：互联网发布：我是传奇结局知乎编辑：程序博客网时间：2024/05/21 17:00

只要以数组形式来命名表单中的文件上传标记，即可实现多个文件同时上传。

下面我们来看一个例子：
---------------------------------------------------------------------

<form enctype="multipart/form-data" action="<?=$_SERVER['PHP_SELF']?>" method="post">
<input type="hidden" name="MAX_FILE_SIZE" value="104857600" />
<table>
<tr>
<td>上传文件：<input name="upload_file[]" type="file" size="50" /></td>
</tr>
<tr>http://m.nvzi91.cn/gongjingyan/29412.html
<td>上传文件：<input name="upload_file[]" type="file" size="50" /></td>
</tr>
<tr>
<td>上传文件：<input name="upload_file[]" type="file" size="50" /></td>
</tr>
<tr>
<td>上传文件：<input name="upload_file[]" type="file" size="50" /></td>
</tr>
<tr>
<td><input type="submit" name="submit" value="上传"/></td>
</tr>
</table>
</form>

<?php
function upload($file_error, $file_tmp_name, $file_name){
$info = "";
if($file_name == "")
return $info;
switch($file_error){
case UPLOAD_ERR_INI_SIZE:
$info = $file_name. ": 文件大小超过了服务器的限制";
break;
case UPLOAD_ERR_FORM_SIZE:
$info = $file_name. ": 文件大小超过了浏览器的限制";
break;
case UPLOAD_ERR_PARTIAL:
$info = $file_name. ": 只上传了部分文件";
break;
case UPLOAD_ERR_NO_FILE:
$info = $file_name. ": 没有文件被上传";
break;
case UPLOAD_ERR_NO_TMP_DIR:
$info = $file_name. ": 找不到临时文件夹";
break;
case UPLOAD_ERR_CANT_WRITE:
$info = $file_name. ": 文件写入失败";
break;
case UPLOAD_ERR_OK:
$upload_dir = './'.iconv("UTF-8","gb2312",$file_name);
if(file_exists($upload_dir)){
$info = $file_name.": 同名文件已经存在";
}else{
if(move_uploaded_file($file_tmp_name,$upload_dir)){
$info = $file_name.": 文件上传成功";
}else{
$info = $file_name.": 文件上传失败";
}
}
break;
}
return $info;
}

if(isset($_POST['submit'])){
$info = '';
$count = count($_FILES['upload_file']['name']);
for($i=0; $i<$count; ++$i){
if($_FILES['upload_file']['name'][$i] == "")
continue;
$info = upload(
$_FILES['upload_file']['error'][$i],
$_FILES['upload_file']['tmp_name'][$i],
$_FILES['upload_file']['name'][$i]
);
}m.nvzi91.cn
echo $info;
}
?>
