I have these three arrays:
$arr1 = ['one', 'two', 'three'];
$arr2 = ['three', 'four'];
$arr3 = ['two', 'five', 'six', 'seven'];
And this is expected result:
/* Array
(
[0] => one
[1] => two
[3] => three
[4] => four
[5] => five
[6] => six
[7] => seven
)
Here is my solution which doesn't work as expected:
print_r( array_unique( $arr1 + $arr2 + $arr3) );
/* Array
(
[0] => one
[1] => two
[2] => three
[3] => seven
)
How can I do that?
Use this:
array_unique(array_merge($arr1,$arr2,$arr3), SORT_REGULAR);
this will merge the arrays into one, then removes all duplicates
Tested Here
It outputs:
Array
(
[0] => one
[1] => two
[2] => three
[4] => four
[6] => five
[7] => six
[8] => seven
)
I think this will work just fine
$arr1 = ['one', 'two', 'three'];
$arr2 = ['three', 'four'];
$arr3 = ['two', 'five', 'six', 'seven'];
$n_array = array_values(array_unique(array_merge($arr1 , $arr2 , $arr3)));
echo "<pre>";print_r($n_array);echo "</pre>";die;
Output is
Array
(
[0] => one
[1] => two
[2] => three
[3] => four
[4] => five
[5] => six
[6] => seven
)
use array_merge then, array_unique
$arr1 = ['one', 'two', 'three'];
$arr2 = ['three', 'four'];
$arr3 = ['two', 'five', 'six', 'seven'];
print_r(array_unique (array_merge($arr1,$arr2,$arr3)));
Result
Array ( [0] => one [1] => two [2] => three [4] => four [6] => five [7] => six [8] => seven )
Just Do That.. use
array_uniqeDemo: https://eval.in/827705
<?php
$arr1 = ['one', 'two', 'three'];
$arr2 = ['three', 'four'];
$arr3 = ['two', 'five', 'six', 'seven'];
print_r ($difference = array_unique(array_merge($arr1, $arr2,$arr3)));
?>
<?php
$arr1 = ['one', 'two', 'three'];
$arr2 = ['three', 'four'];
$arr3 = ['two', 'five', 'six', 'seven'];
$merge_arr = array_merge($arr1,$arr2,$arr3);
$unique_arr = array_unique($merge_arr);
echo '<pre>';
print_r($unique_arr);
echo '</pre>';
?>
Output
Array
(
[0] => one
[1] => two
[2] => three
[4] => four
[6] => five
[7] => six
[8] => seven
)
