Here are some examples being explained.
switch can host a number or a variable.
After you write the case statement, switch will check and echo the correct case.
Something simple should be $var = ‘incvice’ switch($var) case: ‘incvice’ : echo ‘ok’; break;
Examples from codeacademy.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | <?php
switch (2) {
case 0:
echo 'The value is 0';
break;
case 1:
echo 'The value is 1';
break;
case 2:
echo 'The value is 2';
break;
default:
echo "The value isn't 0, 1 or 2";
}
?> |
2 3 4 5 6 7 8 9 10 11 | <?php
$fruit = "Apple";
switch ($fruit) {
case 'Apple':
echo "Yummy.";
break;
}
?> |
If you don’t want to use switch, you can just use if / elseif / else. It will do the same thing.
Another example from “All On Your Own!” control switch from php course from codeacademy:
2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 | <?php
$var = 'incvice';
switch($var)
{
case 'google':
echo 'google';
break;
case 'yahoo':
echo 'yahoo';
break;
case 'incvice':
echo 'incvice';
break;
default:
echo 'none of the above';
}
?> |
Remember to add “:” at “case”, instead of ending the row with “;”.
