php上传文件并存储到mysql数据库的方法
这篇文章主要介绍了php上传文件并存储到mysql数据库的方法,以完整实例形式较为详细的分析了php操作文件上传与数据库存储的技巧,具有一定参考借鉴价值,需要的朋友可以参考下
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。
