    /* PHP3 Button generator, (c) 2000 by IzzySoft (izzysoft@buntspecht.de)
    * License: GPL (and it would be nice to drop me a note that you find it
    * useful - if you use it. And, of course, I am very interested in
    * enhancements you made to the script!
    *
    * Purpose: generate buttons with text passed by parameter.
    *
    * possible parameters to the script:
    *button- input gif image. Just the part of the filename before the dot.
    *The specified image file is expected in the same directory
    *as this script resides in.
    *font - font to use (1 - 5; 1 is very small, 3 medium, 5 normal size.
    *The script will automatically use a smaller font if text is
    *too long for selected size.) Default: 5
    *text - the text to be put on the button. Will be centered.
    *textcolor - color for the letters. Default: white.
    *in this example code only blue, white and black are defined;
    *but you can add custom colors easily.
    *width,heigth - width and heigth of the button. Useful only if target
    *button should have different size than source image.
    *
    * Example for usage:
    * <IMG SRC="/blog_article/button/button/yellow/amp;text/Example.html">
    * will look for yellow.gif and put the string "Example" on it.
    *
    * I use to have three buttons I normally generate (one displays selected
    * item, one is for mouseover(), and one is the default button). The source
    * images are yellow.gif, white.gif and blue.gif - so my script assumes
    * blue.gif as default if "button=" not specified - you may wish to change
    * this below, it's easy ;)

1.upfile.php文件

<html>
<body>
<title>文件上传</title>
<form enctype="multipart/form-data" action=upload.php method=post>
<input type=file name=upfile size=10><br><br>
<input type=submit value='上载文件'>
</form>
</body>
</html>
2.upload.php
<?
//取得当前日期信息，并连接成为一个字符串
$datetime = getdate();
$time = implode("",$datetime);
//构造文件名
//$filename="uploadfiles/".$time." ".$upfile_name;
$filename="uploadfiles/".$upfile_name;
//将文件实际的存放在服务器上
$copymes = copy($upfile,$filename);
if ($copymes) {
    print("文件上传成功!<br>n");
    print("文件名：$upfile_name<br>n");
    print("上传的文件大小：$upfile_size<br>n");

}
else  print("文件上传失败!<br>n");

if (($upfile_type=="image/gif")||($upfile_type=="image/pjpeg"))
{
//如果是图形文件格式则显之
echo "<p><img src='";
echo $filename;
echo "'height=150 width=150 align=center border=0>";
}
?>

3.请在上面的那个文件所在目录创建一个目录 uploadfiles 就可以了
