Description

A code block is a list of statements grouped as one unit.

Example

The following code group two print statements together and outputs A and B if the sky color is blue.

<?PHP/*from   j av a  2 s  . c  o  m*/

$sky_color = "blue";

if($sky_color == "blue") {
     print("A \n");
     print("B \n");
}

print("Here I am from java2s.com.");

?>
