Vergleichen mehrerer Arrays für die gleichen Werte

Question

Ich habe den folgenden Code, der ein Array erzeugt.

Ich muss dieses Array aufteilen und vergleichen Sie die resultierenden Arrays gegeneinander.

Ich muss nur Arrays vergleichen, die nebeneinander in der Reihenfolge sind.

Also die erste und zweite, zweite und dritte, so weiter ... Ich kann ein anderes Array erstellen, um die Reihenfolge zu speichern, die verglichen werden muss, wenn das hilft. Ich habe nur keine Ahnung, wie ich sie so überprüfen kann.

Das Ziel ist es, sicherzustellen, dass der Arrays auf beiden Seiten voneinander nicht den gleichen $ racer_id enthält

Es ist für ein Scoring-App für eine Rennstrecke und einen Rennfahrer nicht in dem Rennen sein kann, dass man sich nach das andere.

Kann mir jemand einen Schub in die richtige Richtung geben?

** es wird nur eine $ event_id geben, mit mehreren $ class_id und $ racer_id.

     $getEventClasses->bindValue(':event_id', $event_id); 
     $getEventClasses->execute();

Answer 1

erste Antwort

Sie können dies erreichen, indem den aktuellen Renner-ID mit der nächsten racer-ID in Array zu vergleichen ...

<?php 
$InputArray = array(
      17=>array(
         0=>array(0=>95,1=>2), 
         1=>array(0=>350,1=>3), 
         2=>array(0=>493,1=>4), 
         3=>array(0=>493,1=>4) 
        ), 
      18=>array(
         0=>array(0=>56,1=>2), 
         1=>array(0=>89,1=>3), 
         2=>array(0=>52,1=>4) 
        ), 
      ); 

Schleife zum Vergleich Rennfahrer-ID des

foreach($InputArray as $key => $val) 
{ 
    foreach($val as $k => $v) 
    { 
     $nextKey =$k+1; 
     if(array_key_exists($nextKey,$val)) 
     { 
      if($v[0]==$val[$nextKey][0]) 
      { 
        echo "Racer ID ".$v[0]." Mathced in Class ID : ".$key; 
        ////sucess code here if same race id's are there... 
      } 
     } 
    } 
} 
?> 

Dies wird O/P

Racer ID 493 Mathced in Class ID : 17 

Wie im $InputArray Rennfahrer-ID (493) mit dem Index 2 und 3 ist das gleiche in Klassen-ID 17

$InputArray = array(

Finden Sie doppelte Id in zwei benachbarten Klassen

$keys = array_keys($InputArray);///this will give you an array of all the class id's 17,14,8...  
foreach($InputArray as $key => $val) 
{ 
    $racer_ids = array_map(function ($ar) {return $ar['racer_id'];}, $val);///get all the racers from current class 
    $currentKey = array_search($key,$keys); ///get the key for current class in keys array 
    if(array_key_exists($currentKey+1 ,$keys)) //check if next key exist in keys array (key for 14) 
    { 
     $nextKey = $keys[$currentKey+1]; /// value present at next key in keys array 14 is the next key 
     if(array_key_exists($nextKey,$InputArray)) ///check if next key present in $InputArray

Nicht sicher in PHP. Aber so etwas wie diese

for i = 0 to $eventClasses.count - 1 
    { 
     $event = $eventClasses[i]; 

     for j = 0 to $event.count -2 // last race doesnt compare with next 
     { 
      $currentEvent = $event[j] 
      $nextEvent = $event[j+1]; 

      if ($currentEvent[0] == $nextEvent[0]) 
      { 
       echo 'Same driver on next race?' 
      } 
     } 
    }
