How to remove duplicate values from Array in PHP?

It is pretty simple to delete duplicate values from PHP Array. But sometimes we confuse for how can we remove. But PHP provide pre-define function array_unique that can help to remove duplicate values from Array.

array_unique() through we can get only unique value from array. So, you can see bellow example i have 34 value two times but when i use array_unique() then it will return only unique value as bellow output:

Example:

$myArray = [11,34,56,78,34];
$myArrayNew = array_unique($myArray);
print_r($myArrayNew);

Output:

Array
(
    [0] => 11
    [1] => 34
    [2] => 56
    [3] => 78
)
