How can one optimize a switch structure in PHP to handle multiple variable values more efficiently and maintain readability?

To optimize a switch structure in PHP to handle multiple variable values more efficiently and maintain readability, you can use an associative array to map the variable values to specific cases. This approach reduces the number of comparisons in the switch statement and makes the code more concise and easier to read. 

$variable = 'value2';

$cases = [
    'value1' => function() {
        // Handle value1 case
        echo 'Value 1';
    },
    'value2' => function() {
        // Handle value2 case
        echo 'Value 2';
    },
    'value3' => function() {
        // Handle value3 case
        echo 'Value 3';
    }
];

if (array_key_exists($variable, $cases)) {
    $cases[$variable]();
} else {
    // Handle default case
    echo 'Default';
}
