How is a SQL query made with a dash in a variable?

Question

PHP

Good afternoon! Strange problem! At me values ​​in the table are stored with a dash. Let's say 00-0000001. When I make a query in the database directly, everything works! But when I try to apply from php, no! I copy the same request and nothing. It works without variables ... maybe there is some trick?

$user=addslashes($user);
  $query1 = "SELECT * FROM `cat` WHERE `id` like '".$user."'";    
          $result1 = mysql_query($query1);

I also tried using mysql_real_escape_string, didn't help...

Answer 1

$one = 10;
$two = 111111;
$all = $one.'-'.$two;
"SELECT * FROM `cat` WHERE `id` like '".$all."'";
