PHP Remove same value of array

Question

I have arrays and these arrays have same values and I want to remove the same values and print the different values.

Arrays:

Array(
    [0] => Likes
    [7] => Frind
    [8] => USA
)
Array(
    [0] => USA
    [5] => Lools
)
Array(
    [6] => USA
    [12] => Awesome
)

I need to like this:

Array(
    [0] => Likes
    [7] => Frind
    [8] => USA
    [5] => Lools
    [12] => Awesome
)

do the keys of the arrays matter?

First you should merge the arrays:

$merged = array_merge($array1, $array2, $array3);

Then you can use array_unique method

$unique_array = array_unique($merged);

You can pass every arrays to the array_merge method.

Try this

$array1 = ['likes', 'friends', 'USA']
$array2 = ['USA', 'lools']
$array3 = ['USA', 'Awesome']

$temp_array = array_unique(array_merge($array1, $array2));
$final_array = array_unique(array_merge($temp_array, $array2));

If it so pass them directly in array merge parameter there is no need to create an additional variable $temp_arrray

How are you generating the arrays?

Kartikey Pandey Over a year ago

do it like this. make a $final_array = [] and keep on updating in the foreach loop by $final_array = array_unique(array_merge($final_array, $finalarrays))
