php - SQL Variable Inserting INSIDE mysql_query -

i trying make price slider php , sql , have problem when have problem in code

$query = mysql_query("select * price phone_price between" .$from. "and" .$to. ); while($row = mysql_fetch_array($query)){ print $row['phone_name']; print $row['phone_price']; print ''; } 

i want run sql query select * price phone_price between 300 , 500

i making beta version therefore accepting $from , $to values <input> , think making error in inserting variable in mysql_query .

the error -warning: mysql_fetch_array() expects parameter 1 resource, boolean given in c:\xampp\htdocs\login\slide\slide.php on line 28

you have mistake in query. spaces needed after between , and. otherwise php reads query ...between123and1234.... , should better use quotes place vars:

$query = mysql_query("select * `price` `phone_price` between '".$from."' , '".$to."'");
