Is it necessary to include an else statement in an if-else conditional block when each condition starts a new condition?

In an if-else conditional block where each condition starts a new condition, it is not necessary to include an else statement. This is because each condition will be evaluated independently, and only one block of code will be executed based on the condition that evaluates to true. Including an else statement in this scenario would be redundant.

if ($condition1) {
    // Code block for condition 1
}

if ($condition2) {
    // Code block for condition 2
}

if ($condition3) {
    // Code block for condition 3
}
