php

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

<?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); ?>
