Re: Re: alter switch variable inside case?

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". - E

Could you elaborate? In the example I posted, setting foo=step1 in the first case segment does NOT cause execution of the second case segment, as would be the case if it was actually re-evaluating the match upon subsequent case statements. --- CHAILLAN Nicolas <nicos@php.net> wrote: Yes you can. -- Merci de nous avoir choisi. - Thanks you for your choice.

I'd like to be able to modify the switch variable inside a case statement, like this: switch ($foo) { case 'step2':

    do_step2();
    if ($error) $foo='step1'; //repeat step1

break; case 'step1':

    do_step1();

break; case 'a_third_thing':

    do_something_else();

break; } Can you modify the variable ($foo) inside a case statement and have it evaluated for subsequent 'case's like this? If not, I will have to revert to a series of if statements, in which this can be done: if ($foo=='step2') { do_step2(); if ($error) $foo='step1'; } if ($foo=='step1') { do_step1(); } etc. Switch-case seems cleaner, and I'd prefer to stick with it. __________________________________________________ Do You Yahoo!?
