Is there a logical way to do this condition?

I was curious, is there a way to compress this condition with logic :

if($var1 == 'foo' || $var2 == 'foo' OR $var3 == 'foo')

to something more compact like:

if(($var1 ||$var2 || $var3) == 'foo')

I think php don't allow it, but I'm curipous to know if there is a "logic trick" to do something more or less like that (even if the condition is finally longer than the original) ?

After testing out a few possibilities, I think that in_array() is your best option. John's answer is one of those and the original / first answer given; this is just a supplement to.

You could do it this way and setup an array beforehand, if that is what you're looking to do, for any other added variables.

$var1 =  "foo"; // yep
$var2 =  "foo2"; // nope
$var3 =  "foo3"; // nope
$var4 =  "foo"; // yep

$vars = array("$var1","$var2","$var3","$var4");
if (in_array("foo", $vars)) //Founds a match !
{
    echo "Yep";
}

else
{
    echo "Nope";
}

You could have:

if (($var1 == $var2) && ($var2 == $var3)) {
    // hurrah they're the same
}

in_array() can shorten this up a bit:

if (in_array('foo', array($var1, $var2, $var3))) {

}
