PHP IF Statement - Sectioning off multiple conditions

It seems inefficient to me to write multiple conditions to do the same action,,, for example

if ( (condition_one || (condition_two && condition_three) )
{
    // Do this ...
}
elseif ( condition_two && condition_three)
{
    // Do same as before ...
}
else
{
    // Do that ...
}

Would there be a valid approach to accomplishing this? Where condition_two and condition_three have to be executed together but separately from condition_one...

if ( (condition_one || (condition_two && condition_three) )
{
    // Do this ...
}
else
{
    // Do that ...
}

In other words,,, is there some way, that I am unaware of, to do this:

if ( ( $a < $b || ( $a <= $b && $c = $d ) )
{
    echo 'foo';
}
else
{
    echo 'bar';
}  

Rather than this:

if ( ( $a < $b )
{
    echo 'foo';
}
elseif ( $a <= $b && $c = $d )
{
    echo 'foo';
}
else
{
    echo 'bar';
}
