$ I ;}
?>
File 2. Backup. php

$ Query = "select * from $ table ";
// Database query
$ Result = mysql_db_query ("embed", $ query, $ con );
$ Filestr = "<"."? Xml version = "1.0" encoding = "GB2312 "? "."> ";
$ Filestr. = "<". $ table. "s> ";
While ($ row = mysql_fetch_array ($ result ))
// List all records
{$ Filestr. = "<". $ table. "> ";
$ Fields = mysql_list_fields ("embed", $ table, $ con );
$ J = 0;
// $ Num_fields = mysql_field_name ($ fields, $ j );
// Echo $ num_fields;
While ($ j $ num_fields = mysql_field_name ($ fields, $ j );
$ Filestr. = "<". $ num_fields. "> ";
$ Filestr. = $ row [$ j];
$ Filestr. = "";
$ J ;}
$ Filestr. = "";
}
$ Filestr. = "";
Echo $ filestr;
// The following is the file operation code
$ Filename = $ table. ". xml ";
$ Fp = fopen ("$ filename", "w ");
