isset question

[WALoeIII]

How do I check if multiple things are set, I am gettting really frustrated.

if (isset($var1 and $var2 and $var3)) {
do something cool
} else {
don't do something cool
}

do I use and? or commas or what.

Try:

if((isset($var1)) && (isset($var2)) && (isset($var3))) {
blah

Basically 'and' is replaced with '&&'

I think you can only do this on that way:

if (isset($var1) and isset($var2) and isset($var3)) {
do something cool
} else {
don't do something cool
}

But that's my first post here so anyone can correct me

Edit:

Ohhh I'm to slow for this Board
