isset multiple variables

Copy linkTweet thisAlerts:

ey guys.
Is there a way to isset multiple vars in one line so that if just one variable is set then it will return true?
eg.

[CODE]
$var1= “one”;
if (isset($var1, $var2)) {
//do something
}
[/CODE]

I tried the above with no luck. I’m wondering if its ‘&’s or ‘+’s or ‘.’s instead of commas.

if (isset($var1) || isset($var2)) {
//do something
}[/code]
