mini\Validator\ValidationError class

Documentation

Represents validation errors for both scalar values and complex objects

ValidationError provides a unified interface for validation results:

• Stringable: Cast to string for simple error display
• ArrayAccess: Access property errors via $error['fieldName']
• IteratorAggregate: Iterate over property errors with foreach
• JsonSerializable: Export for API responses

Usage

$error = $validator->isInvalid($value);
if ($error) {
    // Scalar value - just echo it
    echo $error; // "Must be at least 3 characters."

    // Object value - access property errors
    echo $error['username']; // "Username is required."
    echo $error['email'];    // "Invalid email format."

    // Iterate all property errors
    foreach ($error as $field => $fieldError) {
        echo "$field: $fieldError\n";
    }

    // Nested objects
    echo $error['address']['city']; // drills down

    // JSON for API responses
    echo json_encode($error);
}
