In the most basic way, it's just created through the constructor.

$arr = new ArrayUtils([1,2,3,4,5]);

echo $arr->join(", "); //1, 2, 3, 4, 5

Same method as Array.from() in java script

$arr = ArrayUtils::from([1,2,3,4,5]);

echo $arr->join(", "); //1, 2, 3, 4, 5

Same method as Array.of() in java script

$arr = ArrayUtils::of(1,2,3,4,5);

echo $arr->join(", "); //1, 2, 3, 4, 5

All methods can be called statically with the suffix From

echo ArrayUtils::joinFrom([1,2,3,4,5], ", "); //1, 2, 3, 4, 5
