Сравнение нескольких массивов для тех же значений

Question

У меня есть следующий код, который создает массив.

Мне нужно разбить этот массив и сравнить полученные массивы друг с другом.

Мне нужно сравнить только массивы, которые находятся рядом друг с другом.

Итак, первое и второе, второе и третье, и так далее. Я могу построить еще один массив, чтобы сохранить порядок, который нужно сравнить, если это поможет. Я просто не знаю, как их проверить.

Цель состоит в том, чтобы гарантировать, что массивы по обе стороны друг друга не содержат один и тот же $ racer_id

Это для приложения скоринга для гоночного трека и один гонщик не может быть в гонках, которые один за другой.

Может кто-нибудь дать мне толчок в правильном направлении?

** будет только один $ event_id, с несколькими $ class_id и $ racer_id.

Answer 1

Первого ответа

Вы можете достичь этого пути сравнения текущего гонщика идентификатор со следующим идентификатором гонщика в массиве ...

<?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) 
        ), 
      ); 

Петли для сравнения гонщик идентификаторов

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... 
      } 
     } 
    } 
} 
?> 

Это будет O/P

Racer ID 493 Mathced in Class ID : 17 

Как и в $InputArray гонщик ид (493) с индексом 2 и 3 такое же в классе ид 17

Не уверен, что в PHP. Но что-то вроде этого

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?' 
      } 
     } 
    }
