我有一些数组的数组,我需要转换为新数组并将所有值与所有先前的值相加.例如(数组长度,键和值总是不同),这就是我所拥有的：
Array
(
[0] => 1
[1] => 1
[2] => 5
[3] => 1
[4] => 1
[7] => 1
[8] => 3
[9] => 1
)
这就是我需要的：
Array
(
[0] => 1
[1] => 2
[2] => 7
[3] => 8
[4] => 9
[7] => 10
[8] => 13
[9] => 14
)
我尝试了许多不同的方法,但总是坚持某些事情,或者意识到我错了.我有一种感觉,我正在尝试重新发明一个轮子,因为我认为必须有一些简单的功能,但没有找到解决方案的运气.这是我尝试的最后一种方式：
$array = array( "0"=> 1,"1"=> 1,"2"=> 5,"3"=> 1,"4"=> 1,"7"=> 1,"8"=> 3,"9"=> 1 );
$this = current($array);
$next = next($array);
$end = next(end($array));
$sum = 0;
$newArray = array();
foreach ($array as $val){
if($val != $end){
$sum = ($this += $next);
array_push($newArray,$sum);
}
}
print_r($newArray);
..不幸的是又错了.我花了很多时间找到方法,不知道我需要去哪里,有人可以把我踢向正确的方向吗？
建议你使用array_slice()& array_sum()
$array = array( "0"=>1,"1"=>1,"2"=>5,"3"=>1,"4"=>1,"7"=>1,"8"=>3,"9"=>1);
$keys = array_keys($array);
$array = array_values($array);
$newArr = array();
foreach ($array as $key=>$val) {
$newArr[] = array_sum(array_slice($array,$key+1));
}
$newArr = array_combine($keys,$newArr);
print '<pre>';
print_r($newArr);
print '</pre>';
输出：
Array
(
[0] => 1
[1] => 2
[2] => 7
[3] => 8
[4] => 9
[7] => 10
[8] => 13
[9] => 14
)
