php向mysql表中添加一条数据(源代码)

php mysql编程的基本步骤:

1. 连接mysql服务器 -- mysql_connect()函数
2. 选择数据库 -- mysql_select_db()函数
3. 执行sql语句 -- mysql_query()函数
4. 如果有数据集返回，还需要处理数据集 -- mysql_fetch_array()函数

知道了PHP操作数据库的步骤，那么要实现php向mysql表中添加一条数据非常简单，请看源码：

<?php
$user = "root";
$pass = "";
$db = "mydatabase";
$link = @mysql_connect( "localhost", $user, $pass );
if ( ! $link ) {
  die( "Couldn't connect to MySQL: ".mysql_error() );
}
/* http://www.manongjc.com/article/1238.html */
print "<h2>Successfully connected to server</h2>\n\n";
@mysql_select_db( $db ) or die ( "Couldn't open $db: ".mysql_error() );
print "Successfully selected database \"$db\"<br />\n";

$query = "INSERT INTO domains( domain, sex, mail )values( 'example.com', 'F', 'a@example.com' )";
print "running query: <br />\n$query<br />\n";
mysql_query( $query, $link ) or die ( "INSERT error: ".mysql_error() );
mysql_close( $link );
?>
