if statement...

wibble999

this could be a very simple answer, and I'm just being dumb / tired, but....

if ($key != "fax")
{
do_stuff();
} ...works fine.

BUT

if ($key != "fax" ¦¦ $key != "address2" ¦¦ $key != "address3")
{
do_stuff();
} ...doesn't work.

I'm getting a parse error on the if statement... does php let me do this kind of multiple check?

Can anyone think of an alternative - basically, I want to "do_stuff" if $key is not equal to one of the 3 above values.

Thanks!

<?
$key = "fax";
if ($key == "fax" or $key == "address2" or $key == "address3")
{
echo "there is a key";
} else {
echo "no key";
}
?>

use OR

thankyou DigitalExpl0it and Sneeze!

I must be tired, because you were both right!

if ($key != "fax" AND $key != "address2" AND $key != "address3") ...is what I was trying to do and worked!

OK - time to turn the PC off, methinks!

Actually you were close on the first one if you really needed an OR in your if statement, you just used the wrong character.

This will work, provided you use the correct OR operator. The pipe symbol is ASCII # 124, the char you used is ASCII # 166, I am not sure what that char is.

if ($key != "fax" || $key != "address2" || $key != "address3")
{
do_stuff();
}

Like I said though, this is assuming you did want and OR and not and AND.

Also, you can use the double ampersand operator in place of AND ...

if ($key != "fax" && $key != "address2" && $key != "address3")
{
do_stuff();
}

how irritating!!!!

I was using the "¦" key found just under the Esc key (on a UK keyboard anyway)

Fortunately, (I guess!), I was wrong anyway and needed && (or AND.....!)

I should explain I'm a Lotus Notes administrator by day, and haven't done serious coding for, oohhhhh, about 7 years!

Thanks!

Just to make it really silly, the pipe character "|" is represented on my keyboard by a broken pipe character "¦" ... it's a US keyboard layout.
