My bad, it should have the query handle as a parameter of course:
$var=107;
$query = mysql_query("SELECT * FROM table WHERE id={$var};") or
die(mysql_error()); // make sure to use double quotes
var_dump(mysql_error(), mysql_num_rows($query));
$var=mysql_real_escape_string("107");
$query = mysql_query("SELECT * FROM table WHERE id={$var};") or
die(mysql_error()); // make sure to use double quotes
var_dump(mysql_error(), mysql_num_rows($query));
$query = mysql_query("SELECT * FROM table WHERE id=107;") or
die(mysql_error()); // make sure to use double quotes
var_dump(mysql_error(), mysql_num_rows($query));
