How can you optimize the code by avoiding repetitive switch statements with similar functionality in PHP?

Repetitive switch statements with similar functionality can be avoided by using arrays to map the cases to their corresponding actions. This approach reduces code duplication and makes it easier to add or modify cases in the future. By using arrays, you can create a more flexible and maintainable code structure. 

// Define an array mapping cases to their corresponding actions
$actions = [
    'case1' => function() {
        // Action for case1
    },
    'case2' => function() {
        // Action for case2
    },
    'case3' => function() {
        // Action for case3
    },
];

// Get the case value
$case = 'case1';

// Execute the corresponding action based on the case value
if (array_key_exists($case, $actions)) {
    $actions[$case]();
} else {
    // Default action
}
