Php 连接到数据库以免费托管时出错

我对免费托管有问题，前一段时间我想连接到在线数据库，但收到错误消息：

Warning: mysql_connect(): A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. 

$ I_DB ["host"] = "mysqlX.000webhost.com"; 
$ I_DB ["user"] = "axx1xxx2_1xxme"; 
$ I_DB ["pass"] = "x857x49"; 
$ I_DB ["name"] = "a9x32_xdex"; 

$ Dbhost = $ i_DB ["host"]; 
$ Dbuser = $ i_DB ["user"]; 
$ Dbpass = $ i_DB ["pass"]; 
$ Dbname = $ i_DB ["name"]; 

mysql_connect ($ dbhost, $ dbuser, $ dbpass) or die (mysql_error ("Sorry error occurred on the connection to the database, while longer <meta Repeat http-equiv='refresh' content='0'>")); 
mysql_select_db ($ dbname) or die (mysql_error ("Sorry error occurred on the connection to the database, while longer <meta Repeat http-equiv='refresh' content='0'>"));

如果能得到帮助，我非常感激。

谢谢。

您必须使用localhost而不是mysqlX.000webhost.com

$ I_DB ["host"] = "mysqlX.000webhost.com";

可能有某些原因，如数据库服务提供商的脱机状态或无法从远程位置设置的本地主机。因此，请尝试与提供商联系。

服务器是否允许远程连接？您可能无法连接到远程数据库。如果数据库是本地的，请更改[主机]=。。。to[host]=LocalHost这不是取决于您尝试连接的MySQL服务器是否位于本地主机上吗？
