[英]How to merge or push or add new key and values to existing array
The array is like this 数组是这样的
Array 1
(
[2014-07-01] => Array
(
[date] => 2014-07-01
[totalr] => 13
)
[2014-07-02] => Array
(
[date] => 2014-07-02
[totalr] => 18
)
//... one for each day of the month
)
An then I have another array very similar to the one before the only key that changes is the key "total" 然后我有另一个数组,该数组与之前唯一更改的唯一键为“ total”的数组非常相似。
Array 2
(
[2014-07-01] => Array
(
[date] => 2014-07-01
[members] => 21
)
[2014-07-02] => Array
(
[date] => 2014-07-02
[members] => 30
)
//... one for each day of the month
)
So with both arrays I need to build a single array, so the final array need to be like this: 因此,对于这两个数组,我都需要构建一个数组,因此最终数组需要像这样:
Final Array
(
[2014-07-01] => Array
(
[date] => 2014-07-01
[totalr] => 13
[members] => 21
)
[2014-07-02] => Array
(
[date] => 2014-07-02
[totalr] => 18
[members] => 30
)
// One for each day of the month
)
the key for each block is the same for each array... I already try array_merge didn't work... so how do I do that?... 每个模块的每个块的键都相同...我已经尝试了array_merge不起作用...所以我该怎么做?

Based on @ChicagoRedSox comment I find this function: 基于@ChicagoRedSox注释,我发现此功能:
function juntaArrs($arr1, $arr2) {
if (!is_array($arr1) or !is_array($arr2)) { return $arr2; }
foreach ($arr2 AS $sKey2 => $sValue2) {
$arr1[$sKey2] = juntaArrs(@$arr1[$sKey2], $sValue2);
}
return $arr1;
}
$new_arr = juntaArrs($a1, $a2);
print_r($new_arr);
it works perfectly!! 它完美地工作! thank you.
谢谢。
// start with a new array
$newArr = array();
// for every key and value in array 1
foreach($arr1 as $k=>$v){
// add in the new array at key each key an array with date (the key),
// totalr (the second value in the sub-array) and numbers (the second value in
// the array 2 at the key position
$newArr[$k] = array('date'=>$k, 'totalr'=>$v[1], 'numbers'=>$arr2[$k][1]);
}
// it's what we obtain
print_r($newArr);
