show_info.php文件如下：

<?php 
   if(!isset($_REQUEST['id']) or $_REQUEST['id']=="") die("error: id none");
  $id = $_REQUEST['id'];
  //定位記錄,讀出
  $conn=mysql_connect("localhost","root","admin");

  if(!$result) die(" error: mysql query");
  //如果沒有指定的記錄，則報(bào)錯
  $num=mysql_num_rows($result);
  if($num<1) die("error: no this recorder");
  //下面兩句程序也可以這么寫
  //$row=mysql_fetch_object($result);
  //$name=$row->name;
  //$size=$row->size;
  $name = mysql_result($result,0,"file_name");
  $size = mysql_result($result,0,"file_size");
  mysql_close($conn);
  echo "<hr>上傳的文件的信息：";
  echo "<br>The file's name - $name";  
  echo "<br>The file's size - $size"; 
  echo "<br><a href=show_add.php?id=$id>附件</a>";
?>

submit.php文件如下：

<?php  
  if(is_uploaded_file($_FILES['myfile']['tmp_name'])) {
  //有了上傳文件了 
  $myfile=$_FILES["myfile"];
    //設(shè)置超時(shí)限制時(shí)間,缺省時(shí)間為 30秒,設(shè)置為0時(shí)為不限時(shí)
    $time_limit=60;     
    set_time_limit($time_limit); //
    //把文件內(nèi)容讀到字符串中
    $fp=fopen($myfile['tmp_name'], "rb");
    if(!$fp) die("file open error");
    $file_data = addslashes(fread($fp, filesize($myfile['tmp_name'])));
    fclose($fp);
    unlink($myfile['tmp_name']); 
    //文件格式,名字,大小
    $file_type=$myfile["type"];
    $file_name=$myfile["name"];
    $file_size=$myfile["size"];
    die($file_type);
    //連接數(shù)據(jù)庫,把文件存到數(shù)據(jù)庫中
    $conn=mysql_connect("localhost","root","admin");
    if(!$conn) die("error : mysql connect failed");
    mysql_select_db("nokiapaymentplat",$conn);
    $sql="insert into receive 
    (file_data,file_type,file_name,file_size) 
    values ('$file_data','$file_type','$file_name',$file_size)";
    $result=mysql_query($sql,$conn);
    //下面這句取出了剛才的insert語句的id
    $id=mysql_insert_id();
    mysql_close($conn);
    set_time_limit(30); //恢復(fù)缺省超時(shí)設(shè)置 
    echo "上傳成功--- ";
    echo "<a href='show_info.php?id=$id'>顯示上傳文件信息</a>";
  }  
  else {  
    echo "你沒有上傳任何文件";  
  }  
?>

upload.php文件如下：

<html>  
<head>  
<title>文件上傳表單</title>  
</head>  
<body>  
<table>  
<form enctype='multipart/form-data' name='myform' action='submit.php' 
method='post'>  
<INPUT TYPE = "hidden" NAME = "MAX_FILE_SIZE" VALUE ="1000000">
<tr><td>選擇上傳文件</td><td>
<input name='myfile' type='file'></td></tr> 
<tr><td colspan='2'><input name='submit' value='上傳'  type='submit'></td></tr>  
</table>  
</body>  
</html>
