I got the following array
array(3) {
[0] =>
array(1) {
'Investment' =>
array(15) {
'id' =>
string(36) "53d64bec-031c-4732-b2e0-755799154b1b" ...
I would like to remove the Investment key and do the new array should be
array(3) {
[0] =>
array(15) {
'id' =>
string(36) "53d64bec-031c-4732-b2e0-755799154b1b" ...
how do I do it?
I would pass the array to array_map as such:
$array = [
[ 'Investment' => [ 'id' => '13d64bec-031c-4732-b2e0-755799154b1b' ] ],
[ 'Investment' => [ 'id' => '23d64bec-031c-4732-b2e0-755799154b1b' ] ],
[ 'Investment' => [ 'id' => '33d64bec-031c-4732-b2e0-755799154b1b' ] ],
[ 'Investment' => [ 'id' => '43d64bec-031c-4732-b2e0-755799154b1b' ] ]
];
$mappedArray = array_map(function($val) {
return $val['Investment'];
}, $array);
You can use array_map() and return the value of the 'Investment' key for each item.
$newArray = array_map(function($item) {
return $item['Investment'];
}, $oldArray);
If you do not want to copy the array, you can possibly try to use array_walk().
Edit: solution using array_walk()
array_walk($oldArray, function(&$item) {
$item = $item['Investment'];
});
store investment array in temp variable and unset as similar as given below
$tempArr = // 0 index of your array
foreach($tempArr as $key=>$val){
if(!empty($val['Investment'])){
$temp = $val['Investment'];
unset($val['Investment']);
$val[] = $temp;
}
}
$array[0]=$array[0]['Investment'];
