Answer 1

Have a look at the structure of your array. The values you are looking for are nested withing several arrays:
$data = array (
'code' => 202,
'message' => 'Accepted',
'data' => array (
'resultMap' => array (
'D3856~H158' => array (
'AppDay' => '*',
'HosTown' => 'Colombo 06',
'SpecName' => 'Physiotherapist/Sports Physiotherapist',
'HosName' => 'Revival Healthcare Services (Pvt)-Colombo',
'SpecializationId' => 333,
'HosCode' => 'H158',
'AppDate' => 'Any',
'DocName' => 'MR CHAMARA MATHANGAWEERA',
'DoctorNo' => 'D3856',
)
)
),
'detailMessage' => 'Success'
);
To print all values for the first record in resultMap:
foreach(current($data['data']['resultMap']) as $key => $value) {
echo $key . " => " . $value . "<br />";
}
You need an additional loop in order to print all records in resultMap.

Answer 2

You can try this working fine
for this fixed array values means below given
foreach($arr['data']['resultMap']['D3856~H158'] as $data)
{
$output="Doctor".$data['DocName']."<br/>";
$output="Doctor".$data['SpecName']."<br/>";
$output="Doctor".$data['HosName']."<br/>";
$output="Doctor".$data['Day']."<br/>";
$output="Doctor".$data['Date']."<br/>";
}
or
The changing array values are given the answer
foreach($arr['data']['resultMap'] as $data)
{
$output="Doctor".$data['DocName']."<br/>";
$output="Doctor".$data['SpecName']."<br/>";
$output="Doctor".$data['HosName']."<br/>";
$output="Doctor".$data['Day']."<br/>";
$output="Doctor".$data['Date']."<br/>";
}
