我有以下数组
array (
1 =>
array (
't' =>
array (
0 => 't1',1 => 't2',2 => 't3',),'c' =>
array (
0 => 'c1',1 => 'c2',2 => 'c3','d' =>
array (
0 => 'd1',1 => 'd2',2 => 'd3',2 =>
array (
'j' =>
array (
0 => 'j1',1 => 'j2',2 => 'j3','m' =>
array (
0 => 'm1',1 => 'm2',2 => 'm3','n' =>
array (
0 => 'n1',1 => 'n2',2 => 'n3',)
我需要输出
array(
1=>array(
't-j'=>array('t1-j1','t2-j2','t3-j3'),'c-m'=>array('c1-m1','c2-m2','c3-m3'),'d-n'=>array('d1-n1','d2-n2','d3-n3')
)
);
而我所做的就是
$i = 0;
$res = [];
foreach($arr[1] as $key => $value){
foreach($arr[2] as $k => $v){
$res[$key.'-'.$k][] = $value[$i].'-'.$v[$i];
}
$i++;
}
但是给我这样的东西呢？
Array
(
[t-j] => Array
(
[0] => t1-j1
)
[t-m] => Array
(
[0] => t1-m1
)
[t-n] => Array
(
[0] => t1-n1
)
[c-j] => Array
(
[0] => c2-j2
)
[c-m] => Array
(
[0] => c2-m2
)
[c-n] => Array
(
[0] => c2-n2
)
[d-j] => Array
(
[0] => d3-j3
)
[d-m] => Array
(
[0] => d3-m3
)
[d-n] => Array
(
[0] => d3-n3
)
)
这对我来说是个窍门：
$array1 = $arr[1];
$array2 = $arr[2];
$result = combineArray($array1,$array2);
var_dump($result);
function combineArray($array1,$array2)
{
$res = [];
foreach ($array1 as $key => $value)
{
$otherArray = array_splice($array2,1 );
$otherKey = array_keys($otherArray)[0];
$smallerResult = array();
foreach ($value as $smallerKey => $smallerValue)
{
$smallerResult[] = $smallerValue . '-' . $otherArray[$otherKey][$smallerKey];
}
$res[$key . '-' . $otherKey] = $smallerResult;
}
return $res;
}
我得到的输出如下：
array(3) {
't-j' =>
array(3) {
[0] =>
string(5) "t1-j1"
[1] =>
string(5) "t2-j2"
[2] =>
string(5) "t3-j3"
}
'c-m' =>
array(3) {
[0] =>
string(5) "c1-m1"
[1] =>
string(5) "c2-m2"
[2] =>
string(5) "c3-m3"
}
'd-n' =>
array(3) {
[0] =>
string(5) "d1-n1"
[1] =>
string(5) "d2-n2"
[2] =>
string(5) "d3-n3"
}
}
