sql - Inset php json encoded array into database -

-

i need insert elements of php encoded array database , i'm stuck. have first used json encode to grab data database using sql query (which did successfully) need able opposite. if i'd appreciate it. it's second day of work , i'm not doing well. following code:

    $usercoords_query  = "select accuracy, longitude, latitude, timestamp                                     userdetails           userid =" . $userid;                   $usercoords_result = mysql_query($usercoords_query);  if (mysql_num_rows($usercoords_result) == 0) {     echo "there no users id of ". $userid; }  else {             $emptyarray=array();     while ($row = mysql_fetch_array($usercoords_result)) {         $accuracy=$row['accuracy'];         $longitude= $row['longitude'];         $latitude=$row['latitude'];         $timestamp= $row['timestamp'];          $queue= array('accuracy:' => $accuracy, 'latitude' => $latitude, 'longitude' => $longitude, 'timestamp' => $timestamp);          array_unshift($emptyarray,$queue); }         $objectresponse = array('coords' => $emptyarray);     echo json_encode($objectresponse);      $json_encoded= json_encode($objectresponse);     $json_decoded= json_decode($json_encoded, true);      $update_query= "insert userdetails (userid, accuracy, latitude, longitude,         timestamp)     values ('".$userid."','".$json_decoded[0]        ['accuracy']."','".$json_decoded[0]['latitude']."',     '".$json_decoded[0]['longitude']."','".$json_decoded[0]['timestamp']."')";      mysql_query($update_query) or die(mysql_error());

i agree chandresh_cool. should use 'true' option decode json encoded string array, otherwise return object.

moreover, file_get_contents() expects filename (with full or relative path). when try give json_encoded string, thinks file name , try open file, which, not exist, , throws error. try give existing filename , see solves problem.

p.s. know should comment, due insufficient points, cannot comment

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
