Variables included in double-quoted strings will be interpolated. Their values will be concatenated into the enclosing strings. For example, two statements in the following PHP script will print out the same string:

<?php 
$variable = "and";
echo "part 1 $variable part 2\n"; 
echo "part 1 ".$variable." part 2\n"; 
?>
