What are the potential pitfalls of using multiple if statements to process input data in PHP?

Using multiple if statements to process input data in PHP can lead to code that is difficult to maintain, read, and debug. It can also result in nested if statements, making the code harder to follow and potentially introducing bugs. To solve this issue, consider using switch statements or creating a mapping array to handle the input data more efficiently. 

// Example using a mapping array to process input data

$input = 'option1';

$actions = [
    'option1' => function() {
        echo 'Option 1 selected';
    },
    'option2' => function() {
        echo 'Option 2 selected';
    },
    'option3' => function() {
        echo 'Option 3 selected';
    }
];

if (array_key_exists($input, $actions)) {
    $actions[$input]();
} else {
    echo 'Invalid option selected';
}
