PHP同时连接多个mysql数据库示例代码

在mysql_query函数中指定所用连接，即：

<?php

$conn1 = mysql_connect("127.0.0.1", "root","root","db1");

mysql_select_db("Muma", $conn1); $conn2 = mysql_connect("127.0.0.1", "root","root","db2");

mysql_select_db("product", $conn2);

$sql = "select * from ip";

$query = mysql_query($sql, $conn1); //添加连接$conn1

if($row = mysql_fetch_array($query))

echo $row[0]."\n";

$sql = "select * from web ";

$query = mysql_query($sql, $conn2);

if($row = mysql_fetch_array($query))

echo $row[0];

?>
