UnitEnum::cases — Generates a list of cases on an enum
This method will return a packed array of all cases in an enumeration, in order of declaration.
This function has no parameters.
An array of all defined cases of this enumeration, in order of declaration.
Example #1 Basic usage
The following example illustrates how enum cases are returned.
<?php
enum Suit
{
case Hearts;
case Diamonds;
case Clubs;
case Spades;
}
var_dump(Suit::cases());
?>The above example will output:
array(4) {
[0]=>
enum(Suit::Hearts)
[1]=>
enum(Suit::Diamonds)
[2]=>
enum(Suit::Clubs)
[3]=>
enum(Suit::Spades)
}
If anyone is here wondering how to get all the names from the enum cases and map them into an array, it can be done like this:array_column(CampaignPeriods::cases(), 'name');Likewise, have the 2nd argument as 'value' to get the enum's values.Happy coding, web artisan :)
