Can omitting the break statement after the default case in a PHP switch statement affect the functionality of the code?

Omitting the break statement after the default case in a PHP switch statement can affect the functionality of the code because it will cause the execution to "fall through" to the next case, leading to unintended behavior. To solve this issue, you should include a break statement after the default case to ensure that the switch statement exits after the default case is executed.

switch ($variable) {
    case 'value1':
        // code block
        break;
    case 'value2':
        // code block
        break;
    default:
        // default case code block
        break;
}
