unique()

The unique() method removes duplicate values

Example.php
<?php
use kim\present\utils\arrays\ArrayUtils;
​
$arrayUtils = ArrayUtils::from(["a", "a", "a", "b", "c", "c", "d"]);
​
$arrayUtils->unique();
// expected output: ["a", "b", "c", "d"]
Syntax
$arrayUtils->unique(int $sort_flags = SORT_STRING) : ArrayUtils;
Parameter
$sortFlags 
 
Used to modify the sorting behavior using these values:
​
Sorting type flags:
SORT_REGULAR - compare items normally (don't change types)
SORT_NUMERIC - compare items numerically
SORT_STRING - compare items as strings
SORT_LOCALE_STRING - compare items as strings, based on the current locale.
Return value
A filtered array.
Prefixing
$arrayUtils->uniqueAs(int $sort_flags = SORT_STRING) : array;
ArrayUtils::uniqueFrom(iterable $from, int $sort_flags = SORT_STRING) : ArrayUtils;
ArrayUtils::uniqueFromAs(iterable $from, int $sort_flags = SORT_STRING) : array;
