What are the potential syntax errors that can occur when using the CASE WHEN statement in PHP?

One potential syntax error when using the CASE WHEN statement in PHP is forgetting to include an ELSE statement at the end of the CASE WHEN block. This can cause a syntax error because the CASE WHEN statement requires an ELSE statement to handle cases where none of the conditions are met. To fix this issue, make sure to include an ELSE statement at the end of the CASE WHEN block to handle the default case. 

// Example of using CASE WHEN statement with ELSE statement
$grade = 'A';

switch ($grade) {
    case 'A':
        echo 'Excellent';
        break;
    case 'B':
        echo 'Good';
        break;
    case 'C':
        echo 'Fair';
        break;
    default:
        echo 'Invalid grade';
}
