{"poi":"ytr","wert":"yui","iuyy":"yes"},

{"abc":"qwe","sdsd":"ewewe","fff":"gggg"},

{"poi":"ytr","wert":"yui","iuyy":"yes"},

{"abc":"qwe","sdsd":"ewewe","fff":"gggg"},

{"poi":"ytr","wert":"yui","iuyy":"yes"},

{"abc":"qwe","sdsd":"ewewe","fff":"gggg"}]

Try this..

array_unique() sorts the values treated as string at first, then will keep the first key encountered for every value, and ignore all following keys. It does not mean that the key of the first related value from the unsorted array will be kept.

$getarray=json_decode(yourarray,true);

$array=array_unique($getarray);

You could use the array_unique function, it takes in an array and returns another array without duplicates.

Here is an example :

<?php
$input = array("a" => "green", "red", "b" => "green", "blue", "red");
$result = array_unique($input);
print_r($result);
?>

Your array initialization is wrong, Try this :

    <?php

$array=[["abc"=>"qwe","sdsd"=>"ewewe","fff"=>"gggg"],

    ["poi"=>"ytr","wert"=>"yui","iuyy"=>"yes"],

    ["abc"=>"qwe","sdsd"=>"ewewe","fff"=>"gggg"],

    ["poi"=>"ytr","wert"=>"yui","iuyy"=>"yes"],

    ["abc"=>"qwe","sdsd"=>"ewewe","fff"=>"gggg"],

    ["poi"=>"ytr","wert"=>"yui","iuyy"=>"yes"],

    ["abc"=>"qwe","sdsd"=>"ewewe","fff"=>"gggg"]

];
$unique=array(); 
$sorted_unique=array(); 
    for($n=0;$n<count($array);$n++) 
    { 
        $unique[]=serialize($array[$n]); 
    } 
    $array1=array_unique($unique); 
    for($n=0;$n<count($array1);$n++) 
    { 

            $sorted_unique[]=unserialize($array1[$n]); 

    } 
var_dump($sorted_unique);

?>
