You have to do something like this:你必须做这样的事情:
$user="username";
$password="password";
$con=mysql_connect('10.10.10.10',$user,$password);
$db_selected = mysql_select_db("database_name", $con) or die("DB connecting problem");
<?php
$user="uname";
$pwd="pwd";
$con = mysql_connect("localhost",$user,$pwd);
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
// Create database
if (mysql_query("CREATE DATABASE my_db",$con))
{
echo "Database created";
}
else
{
echo "Error creating database: " . mysql_error();
}
$selectdb = mysql_select_db("my_db", $con);
if (!$selectdb)
{
die('Database Not selected.');
}
mysql_close($con);
?>
Katty, you could head to the official PHP function reference page for MySQL which is: Katty,您可以访问 MySQL 的官方 PHP function 参考页面:
http://php.net/manual/en/ref.mysql.php http://php.net/manual/en/ref.mysql.php
initially focus on mysql_connect().最初专注于 mysql_connect()。 There's also some community submitted content, which could come handy for testing.
还有一些社区提交的内容,可以方便地进行测试。
Also if you could provide the code u are using and error thrown, that would help.此外,如果您可以提供您正在使用的代码并抛出错误,那将有所帮助。
