What potential pitfalls can arise when using if..elseif.. conditions in PHP?

One potential pitfall when using if..elseif.. conditions in PHP is forgetting to include a default condition or handling for all possible cases. This can lead to unexpected behavior if none of the conditions are met. To solve this, always include a final else block to handle any cases that are not covered by the if or elseif conditions. 

$number = 5;

if ($number == 1) {
    echo "Number is 1";
} elseif ($number == 2) {
    echo "Number is 2";
} else {
    echo "Number is not 1 or 2";
}
