What are the best practices for handling multiple conditions in a switch case statement in PHP?

When handling multiple conditions in a switch case statement in PHP, it is best to use fall-through cases to group similar conditions together. This helps to keep the code clean and easy to read, as well as avoid repetition of code for similar cases.

switch ($condition) {
    case 'condition1':
    case 'condition2':
        // Code for condition1 and condition2
        break;
    case 'condition3':
        // Code for condition3
        break;
    default:
        // Default case
        break;
}
