The solution of PHP sending mobile MAS SMS garbled code

Mobile agents need to be used in the project MAS Interface development of SMS , But the development kit provided by the manufacturer does not PHP Of , Only use DB Interface , Direct manipulation MYSQL. But after the text message is sent , The SMS received by the mobile phone is indeed garbled , For a long time , Generally speaking, it should be the problem of character coding . Keep thinking in this direction 、 experiment , Finally, the reason is found out .

1、 Log in to mas The machine mysql database ,
Use command ：show variables like "%char%";
see mysql Character encoding of the database ：
 
 2、php Use as follows ：

mysql_connect('IP:3306','user','pwd');
mysql_select_db('mas');
mysql_query("set names latin1;");
mysql_query(mb_convert_encoding("insert into api_mt_db01(mobiles,content)values('".$mobiles."','".$content."');", "GB2312","UTF-8")); 
  among set names latin1 Equate to
 SET character_set_client = latin1;      

SET character_set_results = latin1;     

SET character_set_connection = latin1; 
3、 The character code in the project is UTF-8, The operating environment is windows 2008 , Its character code is GB2312,
because latin1 and utf8 Character set incompatible , Conversion irreversible , So we must put utf8 Turn into gb2312, And then GB2312 Turn into latin1

So the information input path ：app->os->client->connection->mysql, Code conversion process utf8->gb2312->latin1->latin1->latin1
