For two-dimensional array you can check duplicate value by following.

$array = array();
$temp_array=array();
$array[0]['value']='Dummy';
$array[0]['key']='1';
$array[1]['value']='Dummy';
$array[1]['key']='2';
$array[2]['value']='Not Dummy';
$array[2]['key']='3';

foreach($array as $k=>$step1){
    if(in_array($step1['value'],$temp_array)){
        // In this you can find out duplicate values.
    }
    $temp_array[$k]=$step1['value'];
}

thank everyone for help.

I found the way for fix it now.

I'm not sure it 's best way but It can fix this problem for me.

$data = Array
(
    [0] => Array
        (
            [value] => Dummy
            [key] => 5501____I2-6
        )

    [1] => Array
        (
            [value] => Dummy
            [key] => 5497____I2-2
        )

    [2] => Array
        (
            [value] => Dummy
            [key] => 5502____I2-7
        )

    [3] => Array
        (
            [value] => Dummy
            [key] => 5499____I2-4
        )

    [4] => Array
        (
            [value] => Dummy
            [key] => 5496____I2-1
        )

    [5] => Array
        (
            [value] => Dummy
            [key] => 5500____I2-5
        )

    [6] => Array
        (
            [value] => Dummy
            [key] => 5503____I2-8
        )

    [7] => Array
        (
            [value] => Dummy
            [key] => 5498____I2-3
        )

)

$newarray = array();
  for ($i=0; $i < count($data); $i++) {
     array_push($newarray,$json_data[$i]['value']);
}
if (count(array_unique($newarray)) == 1){
   echo 'The same';
 }
else{
   echo 'not The same';
}

how to check if value in mutidimension array are the same?
