Issues related to generating static files using Smarty

What is the problem of generating static files with Smarty? Require (& quot ;.. /inc/fuction. php & quot;); require (& quot ;.. /inc. php & quot;); require (& quot ;.. /inc/db. php & quot;); require & nbsp; (what is the problem of generating static files with Smarty?
Require ("../inc/fuction. php ");
Require ("../inc. php ");
Require ("../inc/db. php ");
Require ("../Smarty. class. php ");

$ Id = $ _ GET ['id'];
If (isset ($ id) & is_numeric ($ id ))
{
$ Db = new F2MysqlClass ($ dbhost, $ dbuser, $ dbpw, $ dbname );
$ SQL = "select * from news where id = '$ ID '";
$ Result = $ db-> fetchArray ($ db-> query ($ SQL ));
$ Tmp = new Smarty;

$ Tmp-> template_dir = "../smarty/templates ";
$ Tmp-> compile_dir = "../smarty/templates/templates_c ";
$ Tmp-> config_dir = "../smarty/templates/config ";
$ Tmp-> cache_dir = "../smarty/templates/cache ";

If (! Empty ($ result ))
{
$ Tmp-> assign (array (
"Title", htmlspecialchars ($ result ["title"]),
"Name", $ result ["author"]);
}
$ Tmp-> display ('index. tpl ');
$ This_my_f = ob_get_contents (); // key here
Ob_end_clean ();
$ Filename = "$id.html ";
If (tohtmlfile_cjjer ($ filename, $ this_my_f ))
Echo "generated successfully $ filename ";
Else
Echo "generate recognition ";

}

// Write the function of the file generation process
Function tohtmlfile_cjjer ($ file_cjjer_name, $ file_cjjer_content)
{
If (is_file ($ file_cjjer_name )){
@ Unlink ($ file_cjjer_name );
}
$ Cjjer_handle = fopen ($ file_cjjer_name, "w ");
If (! Is_writable ($ file_cjjer_name )){
Return false;
}
If (! Fwrite ($ cjjer_handle, $ file_cjjer_content )){
Return false;
}
Fclose ($ cjjer_handle); // Close the pointer
Return $ file_cjjer_name;
}

Files can be generated. But is the tag in the generated file not replaced? The labels are all blank. What's the problem?
