How can the use of nested IF statements in PHP be improved for better readability and maintenance?

Using nested IF statements can make code difficult to read and maintain. One way to improve this is by using switch statements or restructuring the logic to use elseif statements. This can help make the code more organized and easier to follow.

// Example of restructuring nested IF statements using elseif

if ($condition1) {
    // code block for condition1
} elseif ($condition2) {
    // code block for condition2
} elseif ($condition3) {
    // code block for condition3
} else {
    // default code block
}
