在php开发应用中经常会碰到文件上传,有时也会碰到要多文件上传,下面我们就来看看我提供的三款php多文件上传实例代码,好了费话不说多了来看看这些多文件上传功能适合你么.
示例代码如下:
-
<form action="" method="post" enctype="multipart/form-data" >
-
<input type="file" name="uploadfile[]"> 命名必是这样有"[]"
-
<input type="file" name="uploadfile[]">
-
-
-
$type = array('gif', 'jpg', 'png', 'zip', 'rar');
-
$upload = new uploadfile($_files['uploadfile'], '/', 1024*1024, $type);
-
参数说明:1:表单的文件,2:上传目录,3:支持文件大小,4:允许文件类型
-
$icount = $upload->upload();
-
if($icount > 0) {
-
print_r($upload->getsaveinfo());
-
*/

一个简单实例,代码如下:
-

-
send this file: <input name="userfile[]" type="file" /><br>
-
send this file: <input name="userfile[]" type="file" /><br>
-
send this file: <input name="userfile[]" type="file" /><br>
-
<input type="submit" value="send file" />
-
</form>
-
-
-
<?php
-
-
-
-
$uploaddir = './';
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
-
?>
-
-
-
<?php
-
-
function rearrayfiles(&$file_post) {
-
-
$file_ary = array();
-
$file_count = count($file_post['name']);
-
$file_keys = array_keys($file_post);
-
-
for ($i=0; $i<$file_count; $i++) {
-
foreach ($file_keys as $key) {
-
$file_ary[$i][$key] = $file_post[$key][$i];
-
}
-
}
-
-
return $file_ary;
-
}
-
-
-
print "<pre>";
-
-
if ($_files['userfile']) {
-
$file_ary = rearrayfiles($_files['userfile']);
