php上传文件并存储到mysql数据库的方法

本文实例讲述了php上传文件并存储到mysql数据库的方法。分享给大家供大家参考。具体分析如下：

下面的代码分别用于创建mysql表和上传文件保存到mysql数据库

创建mysql表：

<?php
 $con = mysql_connect("localhost", "", "");
 mysql_select_db("w3m");
 $sql = "create table updfiles ("
   . " id integer not null auto_increment"
   . ", name varchar(80) not null"
   . ", type varchar(80) not null"
   . ", size integer not null"
   . ", content blob"
   . ", primary key (id)"
   . ")";
 mysql_query($sql, $con);
 mysql_close($con);
?>

上传文件并保存到mysql中，通过insert语句插入

<?php
 $con = mysql_connect("localhost", "", "");
 mysql_select_db("w3m");
 $error = $_files['w3img']['error'];
 $tmp_name = $_files['w3img']['tmp_name'];
 $size = $_files['w3img']['size'];
 $name = $_files['w3img']['name'];
 $type = $_files['w3img']['type'];
 print("\n");
 if ($error == upload_err_ok && $size > 0) {
  $fp = fopen($tmp_name, 'r');
  $content = fread($fp, $size);
  fclose($fp);  
  $content = addslashes($content);
  $sql = "insert into fyi_files (name, type, size, content)"
   . " values ('$name', '$type', $size, '$content')";
  mysql_query($sql, $con);
  print("file stored.\n");
 } else {
  print("database save for upload failed.\n");
 }
 print("\n");
 mysql_close($con);
?>

希望本文所述对大家的php程序设计有所帮助。
