我有一个像这样的php数组：

I have a php array that just like this:

Array ( [0] => Array ( [product] => 2 [price] => 30 [qnty] => 1 ) [1] => Array ( [product] => 2 [price] => 30 [qnty] => 1 ) [2] => Array ( [product] => 1 [price] => 250 [qnty] => 1 ) )

，然后我想合并重复的值，添加 qnty 索引值，并按如下所示打印该数组：

and I want to combine the duplicate values, add "qnty" index value and print that array like this:

Array ( [0] => Array ( [product] => 2 [price] => 30 [qnty] =>2 ) [1] => Array ( [product] => 1 [price] => 250 [qnty] => 1 ) )

推荐答案

尝试下面的代码。我假设您的数组名称为 $ products

try the code below. I am assuming the your array name is $products

$merged = array(); foreach($products as $product) { $key = $product['product']; if(!array_key_exists($key, $merged)) { $merged[$key] = $product; } else { $merged[$key]['qnty'] += $product['qnty']; } } echo '<pre>'; print_r($merged); exit;
