I developed a good habit where string delimiters are put at the beginning of a line rather than after.

$sql = "SELECT column1, column2, column3"
     . " FROM tablename"
     . " WHERE id = ?"
     ;

The reason I like having delimiters on the beginning of the line is it makes it very clear that the "next" line is there as a continuation of the previous line. It also makes adding a new line or taking an existing line away very simple.

The same would potentially apply with comma delimiters:

$columns = array( "column1"
                , "column2"
                , "column3"
                ) ;

The same can be true with math operations, logic operations, and others like it:

$total = $baseRate
       - $discount
       + $localTaxes
       + $countyTaxes
       + $stateTaxes
       + $shippingCharge
       + $handlingCharge
       ;
