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。
