A Tour of Decision Making Structures in PHP - SWITCH-CASE statements
(Page 4 of 5 )
As the ?: is an alternative to if-then statements, a switch-case statement provides a cleaner way to code lengthy if-elseif statements where each test checks the same variable.
<?php
$weather = "rain";
echo "The weather forecast calls for $weather. ";
switch ($weather)
{
case "snow":
echo "You'd better bundle up!<br />";
break;
case "rain":
echo "Be sure to bring an umbrella!<br />";
break;
case "wind":
echo "Take the day off and fly a kite!<br />";
break;
default:
echo "Who knows what to expect?<br />";
break;
}
?> |
The comparisons made between the variable in the switch and the values designated by the case keyword. The code block of each case is terminated with break. A default case can be used to designate a piece of code that will execute if no other cases return a true comparison.
