脚本宝典收集整理的这篇文章主要介绍了与PHP的复杂合并功能，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。@H_777_0@
$actual_array = [
'assets' => [1,2,3],'liabilITies' => [1,3,4,5,6],'equity' => [1],'income' => [1,4],'expenses' => [1,3]
];
$merge = [
'balance_sheet' => ['assets','liabilities','equity'],'income' => ['income','exPEnses'],];
self::merge( $merge,$actual_array );
将合并列的函数
public static function merge( array $merges,array $data ) { $Bigger_array_length = 0; $arr = []; $columns = []; foreach ($merges as $key => $merge) { foreach ($merge as $index => $column) { //check which array has bigger length in the iteration if($bigger_array_length < count($data[$column])) $bigger_array_length = count($data[$column]); $columns[] = $column; } //when i die and dump the columns array on its First iterate dd($columns); // assets,liabilities,equity if($bigger_array_length> 0) { $total_columns = count($columns);// on first iteration 3 assets,liabilities and equity for($i = 0; $i < $bigger_array_length; $i++) { // $arr[$key][] = [ $columns[$total_columns - 1] => isset($data[ $columns[$total_columns - 1] ][$i]) ? $data[ $columns[$total_columns - 1] ][$i] : 0,$columns[$total_columns - 2] => isset($data[ $columns[$total_columns - 2] ][$i]) ? $data[ $columns[$total_columns - 2] ][$i] : 0,$columns[$total_columns - 3] => isset($data[ $columns[$total_columns - 3] ][$i]) ? $data[ $columns[$total_columns - 3] ][$i] : 0 ]; } } //when i die and dump on first iteration then it's just fine array:1 [▼ "balance_sheet" => array:6 [▼ 0 => array:3 [▼ "equity" => 1 "liabilities" => 1 "assets" => 1 ] 1 => array:3 [▼ "equity" => 0 "liabilities" => 2 "assets" => 2 ] 2 => array:3 [▼ "equity" => 0 "liabilities" => 3 "assets" => 3 ] 3 => array:3 [▼ "equity" => 0 "liabilities" => 4 "assets" => 0 ] 4 => array:3 [▼ "equity" => 0 "liabilities" => 5 "assets" => 0 ] 5 => array:3 [▼ "equity" => 0 "liabilities" => 6 "assets" => 0 ] ] ] $columns = []; } }
我只是被困在这里,无法弄清楚如何让它变得动态.
[$total_columns - 1] // the 1,3 or so on //something like [$total_columns - $i]
因此,如果我让foreach进行第二次迭代,那么它会输出未定义的索引错误.
e.x [$total_columns – 3]将在第二次迭代时产生-1索引,因为第二次迭代只有2个总列.
这将导致未定义的偏移量：-1.
我想要实现的目标
"balance_sheet" => array:6 [▼
0 => array:3 [▼
"equity" => 1
"liabilities" => 1
"assets" => 1
]
1 => array:3 [▼
"equity" => 0
"liabilities" => 2
"assets" => 2
]
2 => array:3 [▼
"equity" => 0
"liabilities" => 3
"assets" => 3
]
3 => array:3 [▼
"equity" => 0
"liabilities" => 4
"assets" => 0
]
4 => array:3 [▼
"equity" => 0
"liabilities" => 5
"assets" => 0
]
5 => array:3 [▼
"equity" => 0
"liabilities" => 6
"assets" => 0
]
],"income" => array:4 [▼
0 => array:2 [▼
"expenses" => 1
"income" => 1
]
1 => array:2 [▼
"expenses" => 2
"income" => 2
]
2 => array:2 [▼
"expenses" => 3
"income" => 3
]
3 => array:2 [▼
"expenses" => 0
"income" => 4
]
]
]
任何帮助将非常感激.
谢谢
function spec_merge($arr) {
// find max length of array items
$m = max(array_map(count,$arr));
// fill array items to max length by 0
$a = array_map(function($i) use($m) {
return ($m - count($i)) ?
$i + array_fill(count($i),$m - count($i),0) :
$i; },$arr);
// make array of sourse keys
$keys = array_keys($a);
// transpose array
array_unshift($a,null);
$a = call_user_func_array("array_map",$a);
// set correct keys
$a = array_map(function ($i) use($keys) {
return array_combine($keys,$i); },$a);
return $a;
}
$new = spec_merge([
'assets' => [1,'equity' => [1]
]);
PRint_r($new);
结果
[[
[assets] => 1
[liabilities] => 1
[equity] => 1
][
[assets] => 2
[liabilities] => 2
[equity] => 0
][
[assets] => 3
[liabilities] => 3
[equity] => 0
][
[assets] => 0
[liabilities] => 4
[equity] => 0
][
[assets] => 0
[liabilities] => 5
[equity] => 0
][
[assets] => 0
[liabilities] => 6
[equity] => 0
]]
