add it in the PHP file or the html file which calls it?
No,sory ,it doesn't work.The Html code shows as below:<html> <head> <title>First Program</title> </head> <body> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <form action="send.php"> <input type="submit" value="SendSMS!"> <input type=TEXT name="Msg"> </form> </body> </html>And send.php will send the characters in Msg,it still show a pile of chaotic things when I receive it.
