<?php
/* Connect to a MySQL server 连接数据库服务器 */
$link = mysqli_connect(
'localhost', /* The host to connect to 连接MySQL地址 */
'user', /* The user to connect as 连接MySQL用户名 */
'password', /* The password to use 连接MySQL密码 */
'world'); /* The default database to query 连接数据库名称*/
if (!$link) {
printf("Can't connect to MySQL Server. Errorcode: %s ", mysqli_connect_error());
exit;
}
/* Send a query to the server 向服务器发送查询请求*/
if ($result = mysqli_query($link, 'SELECT Name, Population FROM City ORDER BY Population DESC LIMIT 5')) {
print("Very large cities are: ");
/* Fetch the results of the query 返回查询的结果 */
while( $row = mysqli_fetch_assoc($result) ){
printf("%s (%s) ", $row['Name'], $row['Population']);
}
/* Destroy the result set and free the memory used for it 结束查询释放内存 */
mysqli_free_result($result);
}
/* Close the connection 关闭连接*/
mysqli_close($link);
