I'm not sure if you've already tried the idea I posted earlier. Anyway, I
tried it myself and it works! (At least with this simple example...)
<!-- whatevername.php -->
<?php
echo 'myvar BEFORE the switch : ' . $_GET['myvar'];
echo '<hr />';
switch ($_GET['myvar']){
case 1: $_GET['myvar'] = 2;
case 2: echo "Hello!<br />"; break;
case 3: $_GET['myvar'] = 4;
case 4: echo "Hello again!<br />"; break;
}
echo '<hr />';
echo 'myvar AFTER the switch : ' . $_GET['myvar'];
?>
<!-- end of whatevername.php -->
Try it. For example,
http://www.your_domain_name.com/whatevername.php?myvar=1
will change myvar to 2 and will echo "Hello!" (without executing the other
"cases"). Then,
http://www.your_domain_name.com/whatevername.php?myvar=3
will change myvar to 4 and will echo "Hello again!".
As you can see, the key is using "break" ONLY in places you want to
"break"...
So, setting the variable in the first (or third) case CAN "cause execution
of the second [or fourth] case segment".
