本文介绍下，php实现文件上传的一个简单例子，以及文件上传错误代码的相关内容，有需要的朋友，可以作个参考。

1，html表单部分

复制代码代码示例:

<html>

 <head>

  <title>php文件上传-www.jb200.com</title>

 </head>

 <body>

  <h3>文件上传</h3>

  选择上传文件:<br>

  <form action="uploader.php" method="post" enctype="multipart/form-data">

  <input type="file" name="file" size="45">

  <br>

  <input type="submit" value="上传文件">

  </form>

 </body>

</html>

2，文件上传程序 uploader.php

复制代码代码示例:

<?php
/**
* 接收文件上传信息
* by www.jb200.com
*/

if( $_FILES['file']['name'] != "" )
{
    copy ( $_FILES['file']['tmp_name'],
     "C:/Apache/htdocs/" . $_FILES['file']['name'] )
    or die( "Could not copy file" );
}
else
{
    die( "No file specified" );
}
?>
<html>
<head>
<title>上传成功</title>
</head>
<body>
<h3>文件上传成功...</h3>
<ul>
<li>文件名称: <?php echo $_FILES['file']['name']; ?></li>
<li>文件大小: <?php echo $_FILES['file']['size']; ?> bytes</li>
<li>文件类型: <?php echo $_FILES['file']['type']; ?></li>
</ul>
<a href="<?php echo $_FILES['file']['name']; ?>">点这里查看文件</a>
