odbc howto break sentence into different lines

Hi,

Just a simple question I´d like to remember. How do you break a sentence into several lines without quotes? Is it possible?

i.e. $st= "SELECT * FROM CUSTOMER WHERE CUSTOMER LIKE 'JOHN%' AND CIA = 'XXXXXXX' ";

break into

$st="SELECT * FROM CUSTOMER

WHERE CUSTOMER LIKE 'JOHN%' AND CIA = 'XXXXXXX' ";

Regards
