diffKey()

The diffAssoc() method all similar to diff(), but this applies to keys

Example.php
<?php use kim\present\utils\arrays\ArrayUtils;

$arrayUtils = ArrayUtils::from(["first" => 1, "second" => 2, "third" => 3]);

//General array comparison
$arrayUtils->diffKey(["first" => 404, "second" => 404]);
// expected output: ["third" => 3]

Syntax

$arrayUtils->diffKey(iterable ...$iterables) : ArrayUtils;

Parameter

  • $iterables

    Arrays to compare.

Return value

  • A array containing all the entries that are not present in any of the other arrays. (Keys are preserved)

Prefixing

$arrayUtils->diffKeyAs(iterable ...$iterables) : array;
ArrayUtils::diffKeyFrom(iterable $from, iterable ...$iterables) : ArrayUtils;
ArrayUtils::diffKeyFromAs(iterable $from, iterable ...$iterables) : array;
