Can I use two || and one && in the same if statement in PHP?

You choose two planets A and B in the selector options to measure the distance.

For example:

if (($planetA == "Nova Terra" || $planetB == "Nova Iaponia") && ($planetA == "Nova Iaponia" || $planetB == "Nova Terra")) 
{ 
    echo "From $planetA to $planet B: 290 parsecs"; 
}

else if (($planetA == "Nova Terra" || $planetB == "Novo Mars") && ($planetA == "Novo Mars" || $planetB == "Nova Terra"))
{ 
    echo "From $planetA to $planet B: 230 parsecs"; 
}

You read "from Nova Terra to Nova Iaponia OR from Nova Iaponia to Nova Terra". To = and.

This is similar to like:

if ($planetA == "Nova Terra" || $planetB == "Nova Iaponia") 
{ 
    echo "From $planetA to $planet B: 290 parsecs"; 
}

else if ($planetA == "Nova Iaponia" || $planetB == "Nova Terra") 
{ 
    echo "From $planetA to $planet B: 290 parsecs"; 
}

else if ($planetA == "Nova Terra" || $planetB == "Novo Mars")
{ 
    echo "From $planetA to $planet B: 230 parsecs"; 
}

else if ($planetA == "Novo Mars" || $planetB == "Nova Terra")
{ 
    echo "From $planetA to $planet B: 230 parsecs"; 
}

You just need to interchange your logical operators to get result you want

if (($planetA == "Nova Terra" && $planetB == "Nova Iaponia") || ($planetA == "Nova Iaponia" && $planetB == "Nova Terra")) 
{ 
    echo "From $planetA to $planet B: 290 parsecs"; 
}

else if (($planetA == "Nova Terra" && $planetB == "Novo Mars") || ($planetA == "Novo Mars" && $planetB == "Nova Terra"))
{ 
    echo "From $planetA to $planet B: 230 parsecs"; 
}
