php while schleife trat

Ich habe die folgenden GPS-Daten, ich versuche, Reisen (Routen) durch den Benutzer basierend auf dem Motorstatus und nach Datum, wo engine=1 ist ein Motorstart und engine=2 ist ein Motor aus Ereignis so weiß ich jedesmal, wenn ich eine engine=2 finde, das Ende einer Reise. Ich muss diese Reisen in einem JSON-Format präsentieren, ich mache das von PHP, aber ich bleibe dran, die tatsächlichen Reisen individuell zu bekommen.php while schleife trat

Jede Hilfe wird geschätzt.

mit einer Spalte mit dem Namen Datum vorsichtig sein, da 'date' a MySQL-Schlüsselwort und so können Sie sich leicht selbst einen Fehler verursachen, wenn Sie ihn nicht korrekt umbrechen oder in SQL-Abfragen umgehen. Gleiches gilt für "Motor". Es ist auf lange Sicht einfacher, wenn Sie eine andere Formulierung für diese Dinge verwenden. – Martin

Danke für den Kommentar, ich werde einige Änderungen an meiner Formatierung vornehmen. – RonEskinder

Sie nie Startlocation haben in Ihr Ergebnis Array, weil $ i ist nie = 1. Die erste Zeile in Ihren Daten haben Zeit = 2016-10-04 10:53:34. Es fügt einen endPoint hinzu, da die engine = 2, $ i = 1 und nach set $ i ++ setzt. Das ist, warum ich $ nie Wert annimmt = 1.

Sie müssen sich bewegen $ i von Schleifenende in $ engine = 1 Block:

while ($result->fetch(PDO::FETCH_BOUND)) { 

      $polylineEncoder->addPoint($lat, $lon); 
      //echo "engine:" . $engine ."\n"; 

      if ($engine == 1) { 
       // Start Location 
       if ($i == 1) { 
        // Add Start Location 
        $startLocation = [ 
         'lat' => $lat, 
         'lon' => $lon, 
         'accuracy' => $accuracy 
        ]; 
        $i++; 
        $points['startLocation'] = $startLocation; 
       } 
      } else if ($engine == 2) { 
       // Add End Location 
       $endLocation = [ 
        'lat' => $lat, 
        'lon' => $lon, 
        'accuracy' => $accuracy 
       ]; 
       $points['endLocation'] = $endLocation; 
       $points['path'] = $polylineEncoder->encodedString(); 
       $i = 1; 
      } 

      $routes[] = $points; 

     }
