Switch statement

[Marcel]

<?php

switch ($var) {

case ("02100" || "02700" || "02500"):

/*
rest of code......
*/

break;

}

?>

Does this work???? (i mean the || statement(s) in combination with a switch
statement?

I don't know if your method works, but traditionally you made use of
switch()'s fall through:

switch($var) {
case "02100":
case "02700":
case "02500":
/* code */
break;
}

Also try to use single quotes instead of double, otherwise the PHP
parser has to parse the contents twice.

switch($var) {
case '02100':
case '02700':
case '02500':
/* code */
break;
}

Sorry for being so lazy...... i figured it out myself....

<?php

$var = "02700";

switch ($var) {

case ("02100" || "02700" || "02500"):

echo "<HR>Yes this works ok!!! (\$var = $var)<HR>";

break;

}

?>

Just like this works?

<?php

$var = "-12345";

switch ($var) {

case ("02100" || "02700" || "02500"):

echo "<HR>Yes this works ok!!! (\$var = $var)<HR>";

break;

}

?>

The result?

"Yes this works ok!!! ($var = -12345)"

.... No it doesn't... Read Luke Ross's post.

Testing is always the best way to get an answer to a question. But you
have to test thoroughly: as John Smith pointed out, this construction
will catch everything. You can see what's happening if you do this:

if ("02100" || "02700" || "02500") {
echo "True";
}

That expression will always evaluate to true. Your case statement then,
is just a long way of writing

case true:
