How to make array intersect in php?

Question

This is my two arrays:

$head_office = array(600,400,534,678,601,90);
$Sb_office = array(600,400,530,678,600,90,84);

My desire output:

array(600,400,678,90);

I am trying:

print_r(array_intersect($Sb_office,$head_office));

Output:

Array ( [0] => 600 [1] => 400 [3] => 678 [4] => 600 [5] => 90 )

How can I avoid the value 600 ?

NB: I am not removing duplicate values. I want to get matched values between 2 arrays.

Assuming that you mean you want to avoid ___duplicating___ the value 600, then there's a magic little function called [array_unique()](http://www.php.net/manual/en/function.array-unique.php): `print_r(arry_unique(array_intersect($Sb_office,$head_office)));` — Mark Baker, May 13 '16 at 13:35
yes it brings one value removing duplicate values. But I want to get matched value between my two arrays. Here, $head_office has only one 600. So after intersect result should have one 600. It is not removing duplicate values. — Asif Iqbal, May 13 '16 at 13:40
Swap $Sb_office and $head_office in array_intersect. The order is important — ml_, May 13 '16 at 13:54

Use array_unique().

$head_office = array(600,400,534,678,601,90);
$Sb_office = array(600,400,530,678,600,90,84);

print_r(array_unique(array_intersect($Sb_office,$head_office)));

Output

Array ( [0] => 600 [1] => 400 [3] => 678 [5] => 90 )

Use array_unique

Additionally you can use array_values to alter the keys of new array.

$head_office = array(600,400,534,678,601,90);
$Sb_office = array(600,400,530,678,600,90,84);

print_r(array_values(array_unique(array_intersect($Sb_office,$head_office))));

OUTPUT

Array ( [0] => 600 [1] => 400 [2] => 678 [3] => 90 )

It seams that you want to avoid duplicate value 600. you can do it using array_unique() like below

print_r(arry_unique(array_intersect($Sb_office,$head_office)));

Swap $head_office and $Sb_office

<?php
$head_office = array(600,400,534,678,601,90);
$Sb_office   = array(600,400,530,678,600,90,84);

print_r( array_intersect($head_office, $Sb_office) );

Output:

Array
(
    [0] => 600
    [1] => 400
    [3] => 678
    [5] => 90
)

I have gotten a partial answer:

print_r( array_intersect_assoc($head_office, $Sb_office) );

Almost! assoc also compares the indexes, which would fail if the values are available in both arrays but on different positions. – ml_ May 13 '16 at 13:53

You need to delete this answer and instead _edit_ your original post to add any more info. – CodeGodie May 13 '16 at 14:09
