The manual for PHP switch shows no examples on how to use multiple values
for the same case.
In liberty basic I would use the following:
case 1,2,3,4
case "A","B","C"

What is the equivelant in PHP?

I use the following code to acquire a value:
$value=$_GET['v'];
switch ($value){
case "A";
echo "Does Not Work!";
case A:
echo "Does Not Work!";
}

So what is the proper way to ensure the proper case is found correctly?

This is fucked up, despite what you may believe ":" is not the same as ";"

You seem to have missed the paragraph beginning "It is important to
understand how the switch statement is executed in order to avoid
mistakes." on the manual page. This paragraph answers your question.

Oh, and just to clarify, you also need to add "I am incapable of
reading." and "I tell lies." to your cv as well.

There is a very clear example on the manual page of matching against
multiple values to execute a single set of statements.

Does this mean we're going to spend the next 5 years debugging your
fucked up switch statements?

I think this is a pretty neat example:
<?php
switch ($i) {
case 0:
case 1:
case 2:
echo "i is less than 3 but not negative";
break;
case 3:
echo "i is 3";
}
?>
found on this page:
http://www.php.net/manual/en/control-structures.switch.php

> In liberty basic I would use the following:

this should be about PHP, not about liberty, or about basic....

: is used for constants.
; is used for strings.

As usuaul, I find the answer to my question.
Instead of commas, use ||.

case 1 || 2 || 3:
case "A" || "B" || "C";

The syntax is correct!

So why not write your site in that language?

It's going to be similar. Above, you've not mixed string and numeric; why
would you do it below?

You've forgotten break and default, and how would you know which was
chosen if both echo statements are identical?

> So what is the proper way to ensure the proper case is found correctly?

switch($nmonth) {
case "01": $cmonth="January"; break;
case "02": $cmonth="February"; break;
case "03": $cmonth="March"; break;
case "04": $cmonth="April"; break;
case "05": $cmonth="May"; break;
case "06": $cmonth="June"; break;
case "07": $cmonth="July"; break;
case "08": $cmonth="August"; break;
case "09": $cmonth="September"; break;
case "10": $cmonth="October"; break;
case "11": $cmonth="November"; break;
case "12": $cmonth="December"; break;
default: $cmonth="Not a valid month number"; break;
}
echo $cmonth;

You should find a new hobby.

From the manual:
"It's possible to use a semicolon instead of a colon after a case like:"

But this has nothing to do with contants or strings, or....?

PHP does not support that method directly as you have discovered.

Under normal circumstances we know that $value is a string, therefor
what is actually in $value is the question. If the code for *case "A"*
is not being executed then $value <> A.

The example above would indicate that there is a CONSTANT A that
$value is compared against. You are mixing problems.

Not true, the online manual simply indicates that a ; may be used
instead of a : period. Don't know why, I'd never do it that way - seems
to add confusion.

There is nothing wrong with that syntax. It is merely an expression
that ends up being true or not. Using : or ; for either case works as
tested.

I should have known that “richard” would find a way to use this
for his trolling, so I should not have suggested the possibility
in <news:4555789(dot)NIToQkNJ70(at)PointedEars(dot)de>. Sorry, my bad.

Yes, I wasn't aware that ; could be used instead of :, however you fucked
up when you said ": is used for constants. ; is used for strings."

Nice to see you're still on form with the fuck-ups.

The syntax may be valid php syntax, but I'll bet any money you like that
the code doesn't do what you expect under all operating conditions,
because you have fucked up yet again.

Here is a simple program which demonstrates your fuck-up:

<?php
function test($x){
echo "testing {$x} for \"fred\", \"jim\" or \"sue\"\n";
switch($x){
case "fred"||"jim"||"sue":echo" match\n";break;
default;echo" no match\n";break;
}
}
$names = array("pete","fred","alan","sue","andy","jim","hank","richard ");
foreach($names as $name)test($name);

Actually he was right all the way up to the exclamation mark on that
line, but then he reverted to traditional richard.

You misspelled "abilities".

I think RtS actually has very high expectations, not only of himself -- witness his dauntless
attempts at problems that are clearly beyond his grasp -- but also of the other members of
this newsgroup, whom he seems to believe are under some sort of obligation to fix all his
errors for him.

I propose that we all agree that the next time RtS insults someone who is trying to help him,
we will all ignore everything he posts until he apologizes.

And yes I know why. :) It returns a boolean value. 0 does not match
but 4 does, "D" also matches. Ha, good catch Denis and Doug!

I should state that because *1 || 2 || 3* and *"A" || "B" || "C"*
will return a boolean (TRUE) value that:

0 (FALSE) fails to match as expected, any other number is considered TRUE.
"" and "0" (FALSE) fails to match as expected, any other non-empty
string is considered TRUE.

In reality the CASE expression hasn't been matched at all - not even
when $value contains 1,2 or 3 or "A","B" or "C". Only the boolean state
of TRUE or FALSE has been compared.

Richard, you will need to use the standard SWITCH...CASE syntax. I
overlooked that simple concept even as I typed it in my response.

To be honest, the trouble with pointing out glaring errors in richardcode
is working out which fish to shoot, because the barrel is so overcrowded.

1) Go to <http://php.net/manual/en>

2) Use the "Search" box to look for "switch"

3) You should find this:

<http://php.net/manual/en/control-structures.switch.php>

Cite:

The statement list for a case can also be empty, which simply passes
control into the statement list for the next case.

<?php
switch ($i) {
case 0:
case 1:
case 2:
echo "i is less than 3 but not negative";
break;
case 3:
echo "i is 3";
}
?>

switch($value)
{
case 1:
case 2:
case 3:
// dosomething
break; // <--- THIS IS IMPORTANT!

case A:
case B:
case C:
// dosomethingelse
break; // <!-- THIS IS IMPORTANT!

default:
// if nothing else matches
}

Nope - unusual - but valid.

According to <http://php.net/manual/en/control-structures.switch.php>, cite:

It's possible to use a semicolon instead of a colon after a case like:

<?php
switch($beer)
{
case 'tuborg';
case 'carlsberg';
case 'heineken';
echo 'Good choice';
break;
default;
echo 'Please make a new selection...';
break;
}
?>
