array_udiff_assoc funksiýasy, birinji massiwde bar we indiki massiwlerde ýok elementleri öz içine alýan massiw yzyna gaýtarýar. Açarlary (indeksleri) deňleşdirmek PHP-niň düzümleýin mehanizmi arkaly, bahalary bolsa ulanyjy tarapyndan berlen callback-funksiýa arkaly amala aşyrylýar.

Sintaksis

array_udiff_assoc(array $array1, array $array2, ..., callable $value_compare_func): array

Mysal

Ulgamlaşdyrylan funksiýa bilen massiwleri deňleşdirmek:

<?php
	function compare($a, $b) {
		return $a <=> $b;
	}

	$array1 = ["a" => "green", "b" => "brown", "c" => "blue"];
	$array2 = ["a" => "green", "b" => "yellow", "d" => "blue"];
	
	print_r(array_udiff_assoc($array1, $array2, "compare"));
?>

Kodyň ýerine ýetiriliş netijesi:

Array
(
	[b] => brown
	[c] => blue
)

Mysal

San indeksler bilen deňleşdirmek:

<?php
	function numCompare($a, $b) {
		return $a - $b;
	}

	$array1 = [10 => "apple", 20 => "banana", 30 => "cherry"];
	$array2 = [10 => "pear", 20 => "banana", 40 => "cherry"];
	
	print_r(array_udiff_assoc($array1, $array2, "strcmp"));
?>

Kodyň ýerine ýetiriliş netijesi:

Array
(
	[10] => apple
	[30] => cherry
)

Mysal

Obýektleri çylşyrymly deňleşdirmek:

<?php
	class Product {
		public $id;
		public $name;
		
		public function __construct($id, $name) {
			$this->id = $id;
			$this->name = $name;
		}
	}

	function objCompare($a, $b) {
		return strcmp($a->name, $b->name);
	}

	$products1 = [
		"p1" => new Product(1, "Laptop"),
		"p2" => new Product(2, "Phone")
	];
	
	$products2 = [
		"p1" => new Product(3, "Tablet"),
		"p3" => new Product(2, "Phone")
	];
	
	print_r(array_udiff_assoc($products1, $products2, "objCompare"));
?>

Kodyň ýerine ýetiriliş netijesi:

Array
(
	[p1] => Product Object
		(
			[id] => 1
			[name] => Laptop
		)
)
