I have always been confused that .e,g in php i have sql statement
$qry = "select * from table where id = $id";
now can i insert "$" directly inside the quotes or i have to use
$qry = "select * from table where id =".$id." ";
or
$qry = 'select * from table where id = $id';
or
$qry = 'select * from table where id = '$id'';
Which is correct
