1. Make table in my SQL for storing the doctor data,

  1. CREATE TABLE IF NOT EXISTS `tbl_doctormaster` (  
  2.   `dm_Id` int(11) NOT NULL AUTO_INCREMENT,  
  3.   `dm_Name` varchar(50) NOT NULL,  
  4.   `dm_Address` varchar(1000) NOT NULL,  
  5.   `dm_MobileNo` varchar(25) NOT NULL,  
  6.   `dm_EmailAddress` varchar(50) NOT NULL,  
  7.   `dm_Password` varchar(100) NOT NULL,    
  8.   `dm_ActiveStatus` int(11) NOT NULL DEFAULT '1',  
  9.   `dm_CreatedDate` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,  
  10.   `dm_UpdatedDate` timestamp NOT NULL,  
  11.   PRIMARY KEY (`dm_Id`)  
  12. ) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;  
2. Now insert data in datable,
  1. INSERTINTO `tbl_doctormaster`(`dm_Id`, `dm_Name`, `dm_Address`, `dm_MobileNo`, `dm_EmailAddress`, `dm_Password`, `dm_ActiveStatus`, `dm_CreatedDate`, `dm_UpdatedDate`)VALUES  
  2. (1,'kapil111','klklkl','89898898','[email protected]','sdfdsf', 2,'2016-01-11 17:09:51','2016-01-11 17:09:51'),  
  3. (2,'Nirav Daraniya','sdfsdfsdfdsf','899898989','[email protected]','sdfsdfsdfds', 1,'2016-01-11 17:10:33','2016-01-11 17:10:33'),  
  4. (3,'aaaaaa11','asss11','89898998911','[email protected]','989988', 2,'2016-01-11 17:14:37','2016-01-11 17:14:37'),  
  5. (4,'l','l','7777777778','[email protected]','7897987', 2,'2016-01-13 19:32:51','2016-01-13 19:32:51');  
3. Now make One PHP file for service give its name “service_getdoctor.php”,
  1. <?php  
  2. $servername = "localhost";  
  3. $username = "root or Username";  
  4. $password = "Your My SQL password";  
  5. $conn = new mysqli($servername, $username, $password);  
  6. mysqli_select_db($conn, "YourDatabaseName");  
  7. $getData = "SELECT `dm_Id`, `dm_Name`, `dm_Address`, `dm_MobileNo`, `dm_EmailAddress`, `dm_ActiveStatus`, `dm_CreatedDate`, `dm_UpdatedDate` FROM `tbl_doctormaster`";  
  8. $result = mysqli_query($conn, $getData);  
  9. $cnt = 0;  
  10.   
  11. while ($r = mysqli_fetch_row($result))  
  12.     {  
  13.     $cnt = 1;  
  14.     $msg[] = array(  
  15.         "dm_Id" => $r[0],  
  16.         "dm_Name" => $r[1],  
  17.         "dm_Address" => $r[2],  
  18.         "dm_MobileNo" => $r[3],  
  19.         "dm_EmailAddress" => $r[4],  
  20.         "dm_ActiveStatus" => $r[5],  
  21.         "dm_CreatedDate" => $r[6]  
  22.     );  
  23.     }  
  24.   
  25. $json = $msg;  
  26. header('content-type: application/json');  
  27.   
  28. if ($cnt == 0)  
  29.     {  
  30.     $resp["status"] = "-1";  
  31.     $resp["message"] = "Data Not Found";  
  32.     }  
  33.   else  
  34.     {  
  35.     $resp["status"] = "1";  
  36.     $resp["data"] = $msg;  
  37.     }  
  38.   
  39. $response["response"] = $resp;  
  40. echojson_encode($response);  
  41. @mysqli_close($conn);  
  42. ?>  
4. Now run this php file(service it give below output),

{"response":{"status":"1","data":[{"dm_Id":"1","dm_Name":"kapil111","dm_Address":"klklkl","dm_MobileNo":"89898898","dm_EmailAddress":"[email protected]","dm_ActiveStatus":"2","dm_CreatedDate":"2016-01-11 22:39:51"},{"dm_Id":"2","dm_Name":"Nirav Daraniya","dm_Address":"sdfsdfsdfdsf","dm_MobileNo":"899898989","dm_EmailAddress":"[email protected]","dm_ActiveStatus":"1","dm_CreatedDate":"2016-01-11 22:40:33"},{"dm_Id":"3","dm_Name":"aaaaaa11","dm_Address":"asss11","dm_MobileNo":"89898998911","dm_EmailAddress":"[email protected]","dm_ActiveStatus":"2","dm_CreatedDate":"2016-01-11 22:44:37"},{"dm_Id":"4","dm_Name":"l","dm_Address":"l","dm_MobileNo":"7777777778","dm_EmailAddress":"[email protected]","dm_ActiveStatus":"2","dm_CreatedDate":"2016-01-14 01:02:51"}]}}
