PHP not exiting loop -

-

im trying return data php based on time. ie if current time greater publish time post data should sent user else should told that's scheduled.. problem if condition met still executes loop , gives 'success' result.any idea how overcome this? 

$sql = "select posts.post_title,posts.author_name,posts.publish_date,posts.post_content,comments.name,comments.comment,comments.time_posted "         . "from posts left join comments "         . "on posts.id=comments.post_id "         . "where posts.id=$data->id "         . "limit 5";     $result = mysql_query($sql) or trigger_error(mysql_error() . $sql);     $count = mysql_num_rows($result);     $index = 0;     if ($count >= 1) {         $temp = array();         while ($row = mysql_fetch_assoc($result)) {              if (strtotime($data->now) > strtotime($row['publish_date'])) {                 if ($index == 0) {                     $results[$index]['post_title'] = $row['post_title'];                     $results[$index]['author_name'] = $row['author_name'];                     $results[$index]['publish_date'] = $row['publish_date'];                     $results[$index]['post_content'] = $row['post_content'];                      $temp[$index]['name'] = $row['name'];                     $temp[$index]['comment'] = $row['comment'];                     $temp[$index]['time_posted'] = $row['time_posted'];                 } else {                     $temp[$index]['name'] = $row['name'];                     $temp[$index]['comment'] = $row['comment'];                     $temp[$index]['time_posted'] = $row['time_posted'];                 }                 $index++;             } else {                 $response['status'] = 'scheduled';                 $response['message'] = 'data present';                 break;             }           }         $results[0]['comments'] = $temp;         $response['status'] = 'success';         $response['message'] = 'data present';         $response['results'] = $results;      } else {         $response['status'] = '404';         $response['message'] = 'post not exist';     }     echo json_encode($response);

so managed solve using flag variable 

$flag = true;     if ($count >= 1) {         $temp = array();         while ($row = mysql_fetch_assoc($result)) {              if ((strtotime($data->now) > strtotime($row['publish_date'])) == true) {                 if ($index == 0) {                     $results[$index]['post_title'] = $row['post_title'];                     $results[$index]['author_name'] = $row['author_name'];                     $results[$index]['publish_date'] = $row['publish_date'];                     $results[$index]['post_content'] = $row['post_content'];                      $temp[$index]['name'] = $row['name'];                     $temp[$index]['comment'] = $row['comment'];                     $temp[$index]['time_posted'] = $row['time_posted'];                 } else {                      $temp[$index]['name'] = $row['name'];                     $temp[$index]['comment'] = $row['comment'];                     $temp[$index]['time_posted'] = $row['time_posted'];                 }                 $index++;             } else {                 $flag = false;             }         }         if ($flag == false) {             $response['status'] = 'scheduled';             $response['message'] = 'data present';         } else {             $results[0]['comments'] = $temp;             $response['status'] = 'success';             $response['message'] = 'data present';             $response['results'] = $results;         }

suddenly have started receiving above error without changes having been made script. host 1and1 (i know...) the script still works fine on different server, , suspicion there must have been server config change has lead this, although hosts plead ignorance. there's no information on above error @ in google can find - have ideas? server running apache if helps. had similar problem. came out of blue. no php code changed. what changed: php upgraded 5.5.25-1 5.5.26. a security risk in php mail() function has been fixed , newlines in additional_headers allowed no more. because newlines mean: starts email message (and surely don't want inject newlines through headers followed evil message). what have worked fine, e.g. having newlines after headers or passing whole message additional_headers , function no more. solution : sanitize headers. no multiple newlines in additional_headers argument. these count "multiple or malformed newlines":...
