Answer 1

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';
}
