This example describes how to batch import data on the refresh page of php. Share it with you for your reference. The specific analysis is as follows:

This function is based on the principle that dedecms generates html pages, but dedecms uses js redirection and refresh for redirection. The effect is the same, let's take a look at a php method to import data in batches.

Because it is definitely not feasible to import million data into the database at a time, so I will import 50 or more data at a time, next time, refresh again to solve the problem. The Code is as follows:

The Code is as follows:

<? Php
Set_time_limit (0 );
// Connect to the database

$ S = isset ($ _ GET ['s '])? $ _ GET ['s']: 0;
$ E = isset ($ _ GET ['E'])? $ _ GET ['E']: 50;
$ Count = 85000;

If ($ s <$ count)
{
$ SQL = "select * from bac_info where isget = 0 order by id desc limit $ s, $ e ";
$ Query = mysql_query ($ SQL );
While ($ rs = mysql_fetch_array ($ query ))
{
$ Id = $ rs ['id'];
$ Sms = $ rs ['ms'];
$ Typeid = $ rs ['typeid'];
$ Isget = $ rs ['isget'];
$ SQL = "insert into bac_info_bak (id, sms, typeid, isget) values ('$ id',' $ sms ',' $ typeid', '$ isget ')";
Mysql_query ($ SQL );
Echo $ SQL;
// Exit;
$ Sqlu = "update bac_info set isget = 1 where id =". $ rs ['id'];
Mysql_query ($ sqlu );
}
Echo' Processing data. The current value is '. $ s ......';
}
Else
{
Echo 'process all data and then sort it randomly ';
}
?>
