Why use POST to submit regular expression string output is only one point??

	$conn = mysql_connect('localhost', 'root', '19aeacv44899d4ff') or die('Could not connect: '.mysql_error());
	mysql_query('set names utf8');
	$db = mysql_select_db('mytest', $conn);
	if (! $db) {
		die("Can\'t use download: ".mysql_error());
	} else {
		if ($_POST) {
			echo $_POST['ListPreg'];
			$sql1 = 'UPDATE `mytest`.`spiders` SET `ListPreg` = "'.$_POST['ListPreg'].'", `ContentPreg` = "'.$_POST['ContentPreg'].
						'"'.', `EnterUrl` = "'.$_POST['EnterUrl'].'" WHERE `spiders`.`ID` = 1 LIMIT 1';
			$result1 = mysql_query($sql1, $conn);
			header('Location: manage.php');
		$sql = 'SELECT * FROM `spiders` LIMIT 0, 30';
		$result = mysql_query($sql, $conn);
		$row = mysql_fetch_array($result);
