BackedEnumCaseTypeMismatch

A backed enum case has a value that doesn’t match the enum’s backing type.

Example

<?php
enum Status: int {
    case Draft = 'draft'; // Error: string value for int-backed enum
    case Published = 1;
}

How to fix

Use values that match the enum’s backing type:

<?php
enum Status: int {
    case Draft = 0;
    case Published = 1;
}

// Or use string-backed enum
enum Status: string {
    case Draft = 'draft';
    case Published = 'published';
}
