PHP array_uintersect() function

The array_uintersect() is an inbuilt function in PHP. It is used to compute the intersection of two or more arrays depending on the values. The first array values are compared with all the other arrays with the help of an user-defined function, and the matches are returned. This function was introduced in PHP 5.0.

Syntax

array array_uintersect ( array $array1 , array $array2 [, array $... ], callable$value_compar_func );

Parameters

Parameter	Description	Is compulsory
array1	Array to compare from.	compulsory
array2	Array to compare against.	compulsory
array3	More arrays to compare against.	Optional
Value_compare_function	Comparison function name.	compulsory

Return

The array_uintersect( ) function returns an array containing the entries from array1 that are present in all of the other arrays.

Example 1

<?php
function callbackfunction($a, $b)
{
if ($a===$b)
{
return 0;
}
return ($a>$b)?1:-1;
}
$test1=array("a"=>"manual", "b"=>"selenium", "d"=>"jmeter");
$test2=array("d"=>"automation", "e"=>"jmeter", "f"=>"beta");
$result=array_uintersect($test1, $test2, "callbackfunction");
print_r($result);
?>

Output:

Array
(
    [d] =>jmeter
)

Example 2

<?php
function userfunction($v1,$v2) 
{
if ($v1===$v2)
	{
		return 0;
	}
return( $v1>$v2)?1:-1;
	}
$lang1=array("a"=>"java","b"=>"c","c"=>"php");
$lang2=array(1=>"java",2=>"c",3=>"csharp");
print_r(array_uintersect($lang1,$lang2,"userfunction"));
?>

Output:

Array
(
    [a] => java
    [b] => c
)

Example 3

<?php
$lang1 = array("a" => "java", "b" => "php", "c" => "perl", "python");
$lang2 = array("a" => "JAVA", "B" => "php", "c", "python");
print_r(array_uintersect($lang1, $lang2, "strcasecmp"));
?>

Output:

Array
(
    [a] => java
    [b] =>php
    [0] => python
)

Example 4

<?php
function callback($v1, $v2) 
	{
		if ($v1 === $v2) 
	{
		return 0;
	} 
		return($v1>$v2)?1:-1;
}
$score1 = array(40, 53, 43, 23);
$score2 = array(53, 40, 42, 43);
$score3 = array(34, 53, 43, 32);
$score_intersect = array_uintersect($score1, $score2, $score3, "callback");
print_r($score_intersect);
?>

Output:

Array
(
    [1] => 53
    [2] => 43
)
