PHP操作MySQL数据库
第一步：连接数据库
$dbhost = 'localhost:3306'; //mysql服务器主机地址
$dbuser = 'guest'; //mysql用户名
$dbpass = 'guest123';//mysql用户名密码
$conn = mysql_connect($dbhost, $dbuser, $dbpass);
if(! $conn )
{
die('Could not connect: ' . mysql_error());
}
echo 'Connected successfully';
第二步：选择数据库
mysql_select_db( 'RUNOOB' );
第三步：进行数据库操作
$sql = "INSERT INTO runoob_tbl ".
"(runoob_title,runoob_author, submission_date) ".
"VALUES ".
"('$runoob_title','$runoob_author','$submission_date')";
mysql_select_db('RUNOOB');
mysql_query( $sql, $connection );
