How can strict typing and comparison in switch case statements impact the functionality in PHP?

Strict typing in switch case statements can impact functionality if the data types of the cases do not match the type of the variable being evaluated. This can lead to unexpected behavior or cases not being matched correctly. To solve this issue, ensure that the data types of the cases match the type of the variable being evaluated, or use type casting to convert the variable to the appropriate type before the switch statement. 

// Example of using strict typing and type casting in switch case statements
declare(strict_types=1);

$number = 1;

switch ((int) $number) {
    case 1:
        echo "Number is 1";
        break;
    case 2:
        echo "Number is 2";
        break;
    default:
        echo "Number is neither 1 nor 2";
}
