In this post, you can remove duplicates from multidimensional array by value in php.

1. Code:

<?php
function getUniqueMultiArray($multiArray){
	$uniqueMyArray =  array_map("unserialize", array_unique(array_map("serialize", $multiArray)));
    return $uniqueMyArray;
} 
$multiArray = array(
      array(
          "name" => "PHP"
      ),
      array(
          "name" => "LARAVEL"
      ),
      array(
          "name" => "PHP"
      )
  );

echo "<pre>";
print_r(getUniqueMultiArray($multiArray));
echo "</pre>"

?>

2. Example:

Input:

$multiArray = array(
      array(
          "name" => "PHP"
      ),
      array(
          "name" => "LARAVEL"
      ),
      array(
          "name" => "PHP"
      )
  );

Output:

Array
(
    [0] => Array
        (
            [name] => PHP
        )
    [1] => Array
        (
            [name] => LARAVEL
        )
)
