 $data= array();
 foreach($itfdatas as $key=>$itfdata)

$checkemps = explode(',',$itfdata['employee_id']);


 $data[] = array(
 'id'=>mysql_real_escape_string($itfdata['P_id']),
 'job_id'=>mysql_real_escape_string($itfdata['quote_id']),
 'job_title'=>mysql_real_escape_string($itfdata['job_title']));



foreach ($checkemps as $checkempss)
 $empusers = $users->ShowAllEmployeeByJobId($checkempss['profile_id']);



 $data[] =array(
 'helper_id'=>mysql_real_escape_string($empusers['profile_id']),
 'helper_name'=>mysql_real_escape_string($empusers['name']));




 

$msg=array('status'=>'success','emp_job_list'=>$data);
$itfresinfo=json_encode($msg);

 

 echo $itfresinfo;

The above code gives the below output

 
 "status": "success",
 "emp_job_list": [
 
 "id": "1",
 "job_id": "MM/IR1",
 "job_title": "2 Men with 4.5 Tonne Truck"
 ,
 
 "helper_id": "1",
 "helper_name": "Vivek" 
 ,
 
 "helper_id": "3",
 "helper_name": "Akhilesh"
 ,
 
 "id": "2",
 "job_id": "MM/IR2",
 "job_title": "This is the test asasascvcvcv"
 ,
 
 "helper_id": "1",
 "helper_name": "Vivek"
 ,
 
 "helper_id": "3",
 "helper_name": "Akhilesh"
 
 ]
 

But I want the below output

 
 "status": "success", 
 "emp_job_list": [ 
 
 "id": "1",
 "job_id": "MM/IR1",
 "job_title": "2 Men with 4.5 Tonne Truck",
 "helper_detail":[ 
 
 "helper_id": "1",
 "helper_name": "Vivek" 
 
 ]

 ,
 
 "id": "1",
 "job_id": "MM/IR1",
 "job_title": "2 Men with 4.5 Tonne Truck",
 "helper_detail":[ 
 
 "helper_id": "1",
 "helper_name": "Vivek" 
 
 ]

 
 ] 
 

Try it like this. But watch out for typos. I haven't tested it.

If this does not work, add to the question a sample of how $itfdatas looks like and one of what $users->ShowAllEmployeeByJobId($checkempss['profile_id']) returns.

$data= array();
foreach($itfdatas as $key=>$itfdata) 
 $employee = array(
 'id' => mysql_real_escape_string($itfdata['P_id']),
 'job_id' => mysql_real_escape_string($itfdata['quote_id']),
 'job_title' => mysql_real_escape_string($itfdata['job_title'])
 'helper_detail' => array();
 );
 $checkemps = explode(',',$itfdata['employee_id']);
 foreach ($checkemps as $checkempss) 
 $empusers = $users->ShowAllEmployeeByJobId($checkempss['profile_id']);
 $employee['helper_detail'][] = array(
 'helper_id' => mysql_real_escape_string($empusers['profile_id']),
 'helper_name' => mysql_real_escape_string($empusers['name'])
 );
 
 $data[] = $employee;

$msg = array('status' => 'success','emp_job_list' => $data);
$itfresinfo = json_encode($msg);
echo $itfresinfo;
