array_intersect_uassoc funksiyasi

array_intersect_uassoc funksiyasi massivlarni solishtiradi va barcha massivlarda mavjud bo‘lgan elementlarni qaytaradi, kalitlarni solishtirish uchun callback-funksiyadan foydalanadi. Birinchi parametr - asosiy massiv, keyingilari - solishtirish uchun massivlar, oxirgi parametr esa kalitlarni solishtirish uchun callback-funksiyadir.

Sintaksis

phparray_intersect_uassoc(array $array1, array $array2, ..., callable $key_compare_func): array;

Misol

Ikki massivni kalitlarni foydalanuvchi funksiyasi orqali tekshirib solishtiramiz:

php<?php
  $array1 = ['a' => 1, 'b' => 2, 'c' => 3];
  $array2 = ['a' => 1, 'b' => 5, 'c' => 3];
  
  function compareKeys($a, $b) {
    return $a <=> $b;
  }
  
  $res = array_intersect_uassoc($array1, $array2, 'compareKeys');
  print_r($res);
?>

Kodni bajarish natijasi:

php['a' => 1, 'c' => 3]

Misol

Uchta massivni foydalanuvchi tomonidan belgilangan kalit solishtirish funksiyasi bilan solishtiramiz:

php<?php
  $array1 = [1 => 'a', 2 => 'b', 3 => 'c'];
  $array2 = [1 => 'a', 4 => 'b', 3 => 'd'];
  $array3 = [1 => 'a', 3 => 'e'];
  
  function keyCompare($key1, $key2) {
    if ($key1 == $key2) {
      return 0;
    }
    return ($key1 < $key2) ? -1 : 1;
  }
  
  $res = array_intersect_uassoc($array1, $array2, $array3, 'keyCompare');
  print_r($res);
?>

Kodni bajarish natijasi:

php[1 => 'a']
