本文主要是介绍mysqli 连接数据库方法，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
<?php
/* Connect to a MySQL server 连接数据库服务器 */
$link = mysqli_connect(
'localhost', /* The host to connect to 连接MySQL地址 */
'jian', /* The user to connect as 连接MySQL用户名 */
'123456', /* The password to use 连接MySQL密码 */
'jian'); /* The default database to query 连接数据库名称*/
if (!$link) {
printf("Can't connect to MySQL Server. Errorcode: %s ", mysqli_connect_error());
exit;
}else
echo '数据库连接上了！'. "<br/>";
if ($result = mysqli_query($link, 'SELECT id,class,scores FROM jian_scores WHERE scores>60 ')) {
echo('id 班级 分数 '). "<br/>";
/* Fetch the results of the query 返回查询的结果 */
while( $row = mysqli_fetch_assoc($result) ){
echo $row['id'], " ", $row['class'], " ", $row['scores'], "<br/>";
// printf("%s (%s) ", $row['id'],$row['class'], $row['scores']);
}
/* Destroy the result set and free the memory used for it 结束查询释放内存 */
mysqli_free_result($result);
}
/* Close the connection 关闭连接*/
mysqli_close($link);
?>
