PHP unique array by value?

Question

I have an array in PHP that looks like this:

  [0]=>
       array(2) {
           [\"name\"]=>
              string(9) \"My_item\"
           [\"url\"]         


        

Answer 1

Serialisation is very useful for simplifying the process of establishing the uniqueness of a hierarchical array. Use this one liner to retrieve an array containing only unique elements.

$unique = array_map("unserialize", array_unique(array_map("serialize", $input)));
