What are the drawbacks of using a switch-case construct in PHP for assigning values to variables, and how can it be improved for flexibility?

Using a switch-case construct for assigning values to variables in PHP can be cumbersome and lead to repetitive code. To improve flexibility, you can use an associative array to map values to keys, allowing for easier maintenance and scalability. 

$variable = 'key1'; // key to be assigned value
$valueMap = [
    'key1' => 'value1',
    'key2' => 'value2',
    'key3' => 'value3',
];

if (array_key_exists($variable, $valueMap)) {
    $assignedValue = $valueMap[$variable];
} else {
    $assignedValue = 'default value';
}

echo $assignedValue;
