PHP:合并在循环数组 [英] PHP: Merge arrays in loop
本文介绍了PHP:合并在循环数组的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
public function getCheckoutForm(){
$arr = array(
'cmd' => '_cart',
'business' => 'some@mail',
'no_shipping' => '1',
'upload' => '1',
'return' => 'url',
'cancel_return' => 'url1',
'no_note' => '1',
'currency_code' => 'url2',
'bn' => 'PP-BuyNowBF');
$cpt=1;
foreach($this->items as $item){
$arr1[] = array(
'item_number_'.$cpt.'' => $item['item_id'],
'item_name_'.$cpt.'' => $item['item_name'],
'quantity_'.$cpt.'' => $item['item_q'],
'amount_'.$cpt.'' => $item['item_price']
);
$cpt++;
}
return array_merge($arr,$arr1[0],$arr1[1]);
}
这将返回数组这样的:
Array
(
[cmd] => _cart
[business] => some@mail
[no_shipping] => 1
[upload] => 1
[return] => url1
[cancel_return] =>url2
[no_note] => 1
[currency_code] => EUR
[bn] => PP-BuyNowBF
[item_number_1] => 28
[item_name_1] => item_name_1
[quantity_1] => 1
[amount_1] => 5
[item_number_2] => 27
[item_name_2] => item_name_2
[quantity_2] => 1
[amount_2] => 30
)
的问题是,在回$ ARR1 [0]和$ ARR1 [1]是硬$ C $光盘。如果在循环我有2个以上的阵列,可以说0,1,2,3答等等,这code将无法工作。任何想法?也许我的逻辑是错误的compleatly ...
The problem is that in return $arr1[0] and $arr1[1] are hardcoded. And if in loop i have more than 2 arrays, lets say 0,1,2,3 ans so on, this code won't work. Any idea? Maybe my logic is compleatly wrong...
推荐答案
有没有必要在你的循环创建数组 - 只需直接添加新键到第一个数组:
There's no need to create arrays in your loop - just add new keys directly to the first array:
public function getCheckoutForm(){
$arr = array(
'cmd' => '_cart',
'business' => 'some@mail',
'no_shipping' => '1',
'upload' => '1',
'return' => 'url',
'cancel_return' => 'url1',
'no_note' => '1',
'currency_code' => 'url2',
'bn' => 'PP-BuyNowBF'
);
$cpt=1;
foreach($this->items as $item){
$arr['item_number_'.$cpt] = $item['item_id'];
$arr['item_name_'.$cpt] = $item['item_name'];
$arr['quantity_'.$cpt] = $item['item_q'];
$arr['amount_'.$cpt] = $item['item_price'];
$cpt++;
}
return $arr;
}
