Using PHP to query a MDB file, and return JSON

Question

I have a Microsoft Access Database, and I am trying to query the table using PHP, and output valid JSON. I have an equivalent code for a MSSQL database, am I am trying to make m

Answer 1

I use this code to get results from an ODBC query into a JSON array:

$response = null;
$conn = null;

try {
  $odbc_name = 'myODBC'; //<-ODBC connectyion name as is in the Windows "Data Sources (ODBC) administrator"

  $sql_query = "SELECT * FROM table;";

  $conn = odbc_connect($odbc_name, 'user', 'pass');
  $result = odbc_exec($conn, $sql_query);

  //this will show all results:
  //echo odbc_result_all($result);

  //this will fetch row by row and allows to change column name, format, etc:     
  while( $row = odbc_fetch_array($result) ) { 
     $json['cod_sistema'] = $row['cod_sistema'];
     $json['sistema'] = $row['sistema'];
     $json['cod_subsistema'] = $row['cod_subsistema'];
     $json['sub_sistema'] = $row['sub_sistema'];
     $json['cod_funcion'] = $row['cod_funcion'];
     $json['funcion'] = $row['funcion'];
     $json['func_desc_abrev'] = $row['desc_abreviada'];
     $json['cod_tipo_funcion'] = $row['cod_tipo_funcion'];

     $response[] = array('funcionalidad' => $json);
  }

  odbc_free_result($result); //<- Release used resources

} catch (Exception $e) {
   $response = array('resultado' => 'err', 'detalle' => $e->getMessage());
   echo 'ERROR: ',  $e->getMessage(), "\n";
}
odbc_close($conn);
return $response;

And finnally encoding the response in JSON format:

echo json_encode($response);
