在多维数组中搜索

Question

在我的网站上，我有一个通过foreach生成的产品列表，并创建了一个多维数组。

阵列是这样的：（短） http://k44.kn3.net/73194E0F9.jpg

我需要将此多维数组中进行搜索，如果的["model"]重复的值。

总之，我不想用相同的["model"]

阵列显示2个产品做定义：

foreach ($results as $result) { 
    $this->data['products'][] = array(
         'product_id' => $result['product_id'], 
         'model' => $corto, 
         'thumb'  => $image, 
         'Disponibilidad' => $rstock, 
         'name'  => $nombre, 
         'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, 100) . '..', 
         'price'  => $price, 
         'special'  => $special, 
         'tax'   => $tax, 
         'rating'  => $result['rating'], 
         'reviews'  => sprintf($this->language->get('text_reviews'), (int)$result['reviews']), 
         'href'  => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id']) 
         ); 
} 

Answer 1

不是完全干净，但容易和快速不使用任何功能。使用model如表密钥

$this->data['products'][$result['model']] = array(
         'product_id' => $result['product_id'], 

以后可以重新索引阵列array_values

Answer 2

阵列产品是变型产品。未经测试但应该可以工作：

$products // Your product array here 
$models = array(); 
$count = 0; 
foreach ($products as $product) { 
    // If Model Already exits (unset/remove from array) 
    if (in_array($product['model'], $models)) unset($products[$count]); 
    // Add Model Number to Array 
    array_push($models, $product['model']); 
    // Increase Count 
    $count++; 
} 

保持已添加模型的阵列，并且已添加未设置。

更新到你的更新代码：

$models = array(); 
foreach ($results as $result) { 

    // Check if Model exits 
    if (in_array($corto, $models)) continue; 

    $this->data['products'][] = array(
     'product_id' => $result['product_id'], 
     'model' => $corto, 
     'thumb'  => $image, 
     'Disponibilidad' => $rstock, 
     'name'  => $nombre, 
     'description' => utf8_substr(strip_tags(html_entity_decode($result['description'], ENT_QUOTES, 'UTF-8')), 0, 100) . '..', 
     'price'  => $price, 
     'special'  => $special, 
     'tax'   => $tax, 
     'rating'  => $result['rating'], 
     'reviews'  => sprintf($this->language->get('text_reviews'), (int)$result['reviews']), 
     'href'  => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id']) 
    ); 

    // Add Model to array 
    array_push($models, $corto); 

} 

更新由Ryan以提高性能：

$models = array(); 
foreach ($results as $result) { 

    // Check if Model exits 
    if (isset($models[$corto])) continue; 

    $this->data['products'][] = array(
     'product_id' => $result['product_id'], 
     'model' => $corto, 
     ..... 
     'href'  => $this->url->link('product/product', 'path=' . $this->request->get['path'] . '&product_id=' . $result['product_id']) 
    ); 

    // Add Model to array 
    $models[$corto] = true; 

}
