Question

我的Array包含一组Arrays ...

array (size=5)
  0 => 
    array (size=7)
      'BMS' => 
        array (size=2)
          'key' => string 'Boomsoort' (length=9)
          'value' => string 'Naaldhout - gewone den' (length=22)
      'ONT' => 
        array (size=2)
          'key' => string 'Ontwikkelingsfase' (length=17)
          'value' => string 'Middeloud naaldhout (20 - 60j)' (length=30)
      'SLG' => 
        array (size=2)
          'key' => string 'Sluitingsgraad' (length=14)
          'value' => string 'Meer dan 2/3' (length=12)
      'BED' => 
        array (size=2)
          'key' => string 'Bedrijfsvorm' (length=12)
          'value' => string 'Hooghout' (length=8)
      'NISCODE' => 
        array (size=2)
          'key' => string 'Gemeentecode overeenkomstig het NIS' (length=35)
          'value' => string '46021' (length=5)
      'KLASSE' => 
        array (size=2)
          'key' => string 'Bosclassificatie' (length=16)
          'value' => string 'Bos' (length=3)
      'POLNR' => 
        array (size=2)
          'key' => string 'Polygoonnummer' (length=14)
          'value' => string '32239' (length=5)
  1 => 
    array (size=7)
      'BMS' => 
        array (size=2)
          'key' => string 'Boomsoort' (length=9)
          'value' => string 'Loofhout - eik of Amerikaanse eik' (length=33)
      'ONT' => 
        array (size=2)
          'key' => string 'Ontwikkelingsfase' (length=17)
          'value' => string '10' (length=2)
      'SLG' => 
        array (size=2)
          'key' => string 'Sluitingsgraad' (length=14)
          'value' => string 'Meer dan 2/3' (length=12)
      'BED' => 
        array (size=2)
          'key' => string 'Bedrijfsvorm' (length=12)
          'value' => string 'Hooghout' (length=8)
      'NISCODE' => 
        array (size=2)
          'key' => string 'Gemeentecode overeenkomstig het NIS' (length=35)
          'value' => string '46021' (length=5)
      'KLASSE' => 
        array (size=2)
          'key' => string 'Bosclassificatie' (length=16)
          'value' => string 'Bos' (length=3)
      'POLNR' => 
        array (size=2)
          'key' => string 'Polygoonnummer' (length=14)
          'value' => string '32239' (length=5)

我还有一个Array，其中包含Array个键列表，用于在添加新条目时检查主Array（上面的定义）。如果这些键/值已经存在 - 我不想将该项添加到主Array。如果一个或多个键/值没有激发......数组可以添加到主集合中。

  array (size=7)
    'BMS',       
    'ONT',     
    'SLG',
    'BED',      
    'NISCODE',        
    'KLASSE',     
    'POLNR'

情况1 ;添加已在所有已定义键上排除的Array。

array (size=7)
  'BMS' => 
    array (size=2)
      'key' => string 'Boomsoort' (length=9)
      'value' => string 'Loofhout - eik of Amerikaanse eik' (length=33)
  'ONT' => 
    array (size=2)
      'key' => string 'Ontwikkelingsfase' (length=17)
      'value' => string '10' (length=2)
  'SLG' => 
    array (size=2)
      'key' => string 'Sluitingsgraad' (length=14)
      'value' => string 'Meer dan 2/3' (length=12)
  'BED' => 
    array (size=2)
      'key' => string 'Bedrijfsvorm' (length=12)
      'value' => string 'Hooghout' (length=8)
  'NISCODE' => 
    array (size=2)
      'key' => string 'Gemeentecode overeenkomstig het NIS' (length=35)
      'value' => string '46021' (length=5)
  'KLASSE' => 
    array (size=2)
      'key' => string 'Bosclassificatie' (length=16)
      'value' => string 'Bos' (length=3)
  'POLNR' => 
    array (size=2)
      'key' => string 'Polygoonnummer' (length=14)
      'value' => string '32239' (length=5)

情况2 ;在所有已定义的键上添加一个不存在的Array。请注意，BMS键具有主集合尚不知道的value。

array (size=7)
  'BMS' => 
    array (size=2)
      'key' => string 'Boomsoort' (length=9)
      'value' => string 'Unadded value' (length=33)
  'ONT' => 
    array (size=2)
      'key' => string 'Ontwikkelingsfase' (length=17)
      'value' => string '10' (length=2)
  'SLG' => 
    array (size=2)
      'key' => string 'Sluitingsgraad' (length=14)
      'value' => string 'Meer dan 2/3' (length=12)
  'BED' => 
    array (size=2)
      'key' => string 'Bedrijfsvorm' (length=12)
      'value' => string 'Hooghout' (length=8)
  'NISCODE' => 
    array (size=2)
      'key' => string 'Gemeentecode overeenkomstig het NIS' (length=35)
      'value' => string '46021' (length=5)
  'KLASSE' => 
    array (size=2)
      'key' => string 'Bosclassificatie' (length=16)
      'value' => string 'Bos' (length=3)
  'POLNR' => 
    array (size=2)
      'key' => string 'Polygoonnummer' (length=14)
      'value' => string '32239' (length=5)

我正在寻找检查主Array集合的最佳方法，如果它已包含Array，其中需要检查的密钥由其他Array给出。< / p>

我已经尝试循环3 Arrays来互相检查 - 我创建的代码非常强大而且很大。我希望看到一些新的尝试可以让我减少代码行...我所拥有的伪代码

/**
* @Param collection = Global collection
* @Param requirekeystocheck = Array keys to check for excistance
* @Param arraytoadd = Array to be added
* @return Boolean
*/
Function checkExcistArrayOfKeysForArray($collection, $requirekeystocheck, $arraytoadd){
    Loop main Array $collection as $collectionItem
        Loop Array $requirekeystocheck with keys to check as $uniqueKey
            Check if main $collectionItem[$uniqueKey] contains $arraytoadd[$uniqueKey] 
                Check if the values are equal (already present)

    If all values in $requirekeystocheck excist in $collectionItem - the item that needs to be added already excists. 
        Return TRUE 
    If not all values excist - the item can be added
        Return TRUE

}

...谢谢

考虑使用php类。这一切看起来都可以很容易地被替换。该课程可能如下所示：

class myClass {

    public $bms = '';
    public $ont = '';
    public $slg = '';
    public $bed = '';
    public $niscode = '';
    public $klasse = '';
    public $polnr = '';

    function __construct($cData) {
        $this->bms = $cData[0];
        $this->ont = $cData[1];
        $this->slg = $cData[2];
        $this->bed = $cData[3];
        $this->niscode = $cData[4];
        $this->klasse = $cData[5];
        $this->polnr = $cData[6]
    }

    function equals($obj) {
        // this function receives another instance of the class and checks whether both instances are identical
        if ($obj->bms != $this->bms) { return false; }
        if ($obj->ont!= $this->ont) { return false; }
        if ($obj->slg != $this->slg) { return false; }
        if ($obj->bed != $this->bed) { return false; }
        if ($obj->niscode != $this->niscode) { return false; }
        if ($obj->klasse != $this->klasse) { return false; }
        if ($obj->polnr != $this->polnr) { return false; }
        return true;
    }

}

我唯一不确定的是带有“key”和“value”的小数组，你一直在使用它。有没有办法摆脱它？我说不出来，因为我不知道这些价值观的目的。如果你解释他们的感觉，我可能会想象另一个。如果这是不可能的，最好为它创建另一个类（类似于数据类型）：

class myDatatype {

    public $key = '';
    public $value = '';

    public construct __construct($key, $value) 
        $this->key = $key;
        $this->value = $value;
    }

}

myClass中的所有变量然后作为数据获取myClass的一个实例，如下所示：

$example->bms = new myDatatype("Bomsoort", "Somewhat");

向类中添加新值的方式取决于“myClass”变量的类型。以下示例假定您通过“myDatatype”使用了解决方案：

$data = array(/* bms */ new myDatatype("key", "value"), ..., /* polnr */ myDatatype("key", "value"));
$example = new myClass($data);

因为这可能变得非常混乱，想想另一个功能，它采取所有必要的值，并完全按照我上面所写的那样做。 thingy = new myClass（$ data）;

尝试使用array_column搜索数组的数组搜索方法参考下面使用会话

将项目添加到购物车的解决方案

<?php
 session_start();
 $pr_id = $_REQUEST['id'];
 $quantity = isset($_REQUEST['quantity'])?$_REQUEST['quantity']:1;
 if(isset($_REQUEST['action']) && $_REQUEST['action']=='add')
{
  if(isset($_SESSION['cartitems']))
  {
     //find index of an array if it exits then do not add else add to cart and then
    if (!array_key_exists($pr_id,$_SESSION['cartitems']))
    {
        $_SESSION['cartitems'][$pr_id]['id'] = $pr_id;
        $_SESSION['cartitems'][$pr_id]['quantity'] = $quantity;
    }
   }
  else
  {
    $_SESSION['cartitems'][$pr_id]['id'] = $pr_id;
    $_SESSION['cartitems'][$pr_id]['quantity'] = $quantity;     
  }
  $arr = array();
  $arr['count'] = count($_SESSION['cartitems']);
  $arr['message'] = 'Item successFully added';
  echo json_encode($arr);
 }
