ช่วยแก้โค้ดหน่อย $_db = mysql_connect('localhost', 'root', 'root') or die(' -- ');

<?php
	
	$_db = mysql_connect('localhost', 'root', 'root') or die(' -- '); mysql_select_db('NEW', $_db);
	mysql_set_charset('tis620');

	$_sql = sprintf("SELECT name FROM dlt_license_car WHERE id = %d", mysql_real_escape_string(25)); 
	$_query = mysql_query($_sql ,$_db); 
	$_result = mysql_result($_query, 0, 0);
	
	$_unserialized = unserialize($_result); print_r($_unserialized);
	mysql_free_result($_query); mysql_close($_db); 

	$_f = '_serialize.txt'; if(!file_exists($_f)) touch($_f, 0777);
	$_fp = fopen($_f, 'w'); 
	$_fw = fwrite($_fp, $_serialize);

	fclose($_fp);

	// ----- Executed
	$_fc = file_get_contents($_f);
	$_unserialized = unserialize($_fc); print_r($_unserialized);
?>
