PHP5怎么连接不上MySQL数据库？
代码
<?php
$db_host='localhost';
$db_database='120422db_1';
$db_username='root';
$db_password='1234';
?>
<?php
include('120422php_1.php');
$connection = mysql_connect($db_host, $db_username, $db_password);
if(!$db_connection){
die ("Could not connect to the database: <br />". mysql_error());
}
?>
结果：Could not connect to the database:
[解决办法]
if(!$db_connection){
用错了变量！
应该是 $connection
