As I will cover this Post with live Working example to develop php compares two arrays for equality, so the php compares two arrays for not matches for this example is following below.

PHP compare keys and values in two arrays

php compare two arrays for matches

$products = array(
	"ajaydevgan",
	"Arti",
	"Bhavika",
	"chandni",
	"Deepa",
	"Elansor",
	"Fakhar Zaman",
	"Geeta"
);

$items = array(

	"Arti",
	"Bhavika",
	"chandni",
	"Deepa",
	"Elansor",
	"Fakhar Zaman",
	"Geeta",
	"Ravi",
	"sanajay"
);

$output = array_intersect($products, $items);
// Expected Output:
// array("Ravi", "sanajay");

$output = array_intersect($products, $items);

PHP – Function array_diff_assoc()

<?php
   $product1 = array( "a"=>"iphone", "b"=>"cpu", "c"=>"remote");
   $product2 = array( "a"=>"iphone", "b"=>"laptop", "c"=>"remote");
   print_r(array_diff_assoc($product1, $product2));
   
   $product1 = array( "a"=>"iphone", "b"=>"cpu", "c"=>"remote");
   $product2 = array( "a"=>"remote", "b"=>"laptop", "c"=>"iphone");
   print_r(array_diff_assoc($product1, $product2));
?>

Output

Array ( [b] => cpu )
Array ( [a] => iphone [b] => cpu [c] => remote )

PHP array_intersect() Function

$products = array("a"=>"mobile","b"=>"green","c"=>"blue","d"=>"computer");
$items = array("a"=>"mobile","b"=>"laptop","h"=>"computer");
$tasks = array("e"=>"mobile","f"=>"laptop","g"=>"purple");
 
$output = array_intersect($products,$items,$tasks);
print_r($output);

PHP compares arrays of keys and values. In this tutorial, you will learn how to PHP compare two or more array keys and values and find the difference between two or more array using the PHP array_diff_assoc() function.

In addition, you will learn about the PHP array_diff_assoc () function, definition, syntax, parameters, and see various examples.

PHP array_diff_assoc()

Definition: array_diff_assoc() function of in-built PHP. Basically, This can be used to get or calculate the difference between one or more arrays in PHP. PHP array_diff_assoc() function compares the keys and values between one or more arrays and returns the difference between them.

Note:- PHP array_diff_assoc() function compares the keys and values of two or more arrays, and it will return an array that contains the entries from array_first that are not present in array_second or array_third, and array_n, etc.

Syntax

Syntax of PHP array_diff_assoc() function is:

array_diff_assoc($array_first, $array_second, $array_third, …, $array_n)

Parameters of array_diff_assoc() function

Parameter	Description
array first	This is the first array of this function and it is required. It is an array to compare from
array second	This is the second array of this function and it is also required. It is an array to be compared with the first array
array n	It’s n array and it is optional. It is an array to be compared with the first array

Example – 1

Now, we will take first example with PHP array_diff_assoc() to compare three arrays keys and values in PHP. Let’s see below:

<?php

$arr1 = array("1"=>"PHP", "2"=>"LARAVEL", "3"=>"CODEIGNITER", "4"=>"WORDPRESS", "5"=>"JOOMLA");

$arr2 = array("1"=>"PHP", "2"=>"LARAVEL", "3"=>"C#", "4"=>"C++");

$arr3 = array("1"=>"PHP", "2"=>"LARAVEL");

print_r(array_diff_assoc($arr1, $arr2, $arr3)); 

?>

The output of the above code is:

 Array ( [3] => CODEIGNITER [4] => WORDPRESS [5] => JOOMLA )

Example – 2

Let’s take the second example, to compare two arrays of keys and values in PHP. And find the difference between them.

<?php

   $arr1 = array( "a"=>"orange", "b"=>"mango", "c"=>"banana");

   $arr2 = array( "a"=>"orange", "b"=>"apple", "c"=>"banana");

   print_r(array_diff_assoc($arr1, $arr2));

?>

The output of the above code is:
