How to get values of enums array in PHP-CodePudding

I would like to applay array_values( $array_of_enums ) on array of enums but I got this error :

Object of class XXXX could not be converted to string in ...

So I wander how to get easily enum values store in an array and NOT all values existing for an enum.

CodePudding user response：

If you are working with an object that represents an enum, you can use the get_object_vars function to extract its properties (which represent the enum values) into an array.

Here's an example:

class MyEnum {
const ENUM_VALUE_1 = 1;
const ENUM_VALUE_2 = 2;
const ENUM_VALUE_3 = 3;
}

$enum = new MyEnum();
$enum_values = array_values(get_object_vars($enum));

print_r($enum_values);

This will output:

Array
(
[0] => 1
[1] => 2
[2] => 3
)

For the moment I create this function :

/**
 * @param UnitEnum[] $array_of_enums
 * @return array|false
 * @throws JsonException
 */
function array_enum_values( array $array_of_enums ){
  $output = [];
  foreach ( $array_of_enums as $enum ){
    if( !$enum instanceof \UnitEnum ){
      error_log( sprintf( "array_enum_values() cannot be executed correctly, one value is not an enum : %s", json_encode( $enum, JSON_THROW_ON_ERROR ) ) );
      return false;
    }else{
      $output[] = $enum->value;
    }
  }
  return $output;
}
