Associative Arrays
Another approach is to use associative arrays to map enum values to their string representations. Here, an associative array $stringMap is used for mapping enum values to their string representations.
<?php
class StatusEnum {
const PENDING = 1;
const APPROVED = 2;
const REJECTED = 3;
private static $stringMap = [
self::PENDING => 'Pending',
self::APPROVED => 'Approved',
self::REJECTED => 'Rejected',
];
public static function toString($enumValue) {
return self::$stringMap[$enumValue] ?? 'Unknown';
}
}
// Driver code
$status = StatusEnum::PENDING;
$statusString = StatusEnum::toString($status);
echo "Status: $statusString";
?>
Output
Status: Pending
PHP Program to Convert Enum to String
Enumerations, or enums are a convenient way to represent a fixed set of named values in programming. In PHP, native support for enums was introduced in PHP 8.1. If you are working with an earlier version of PHP, or if you want to explore alternative approaches, you may need a way to convert enums to strings.
