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。
