I have the following array being returned
Array
(
[0] => Array
(
[uid] => 616941445
)
[1] => Array
(
[uid] => 1354124203
)
)
However I want just a single layered array, so i would like something like this.
Array
(
[0] => 616941445
[1] => 1354124203
)
foreach ($arr as $key => $val) {
$arr[$key] = $val['uid'];
}
$arr[$key] = $val['uid'] which is the same…
<?php
$multi_arr = array(
array(
'uid' => 616941445
),
array(
'uid' => 1354124203
),
);
$single_arr = array();
foreach($multi_arr as $arr){
foreach($arr as $val) $single_arr[] = $val;
}
?>
As always, when you need to change two level array into one level without preserve keys:
$your2DArray = array(/* .. */);
$flatArray = array_map('array_pop', $your2DArray);
And like you want to, no loops.
array_map.foreach($arr as $key=>$val) {
$single_arr[] = $arr[$key]['uid'];
}
