Convert multidimensional array into single array [duplicate]
(24 answers)
Closed 5 years ago.
It's probably beginner question but I'm going through documentation for
longer time already and I can't find any solution and i have an array which
is multidimensional given below format.
/* This is how my array is currently */
Array
(
[0] => Array
(
[0] => Array
(
[title] => a
[title_num] =>1
[status] => 1
)
[1] => Array
(
[title] => Mr
[title_num] => 82
[status] => 1
)
)
[1] => Array
(
[0] => Array
(
[title] => b
[title_num] =>25
[status] => 2
)
[1] => Array
(
[title] => c
[title_num] =>45
[status] => 2
)
)
)
I want to convert this array into this form
/*Now, I want to simply it down to this*/
Array
(
[0] => Array
(
[title] => a
[title_num] =>1
[status] => 1
)
[1] => Array
(
[title] => Mr
[title_num] => 82
[status] => 1
)
[2] => Array
(
[title] => b
[title_num] =>25
[status] => 2
)
[3] => Array
(
[title] => c
[title_num] =>45
[status] => 2
)
)
I have tried array_flatten,array_map PHP built in function
A link or anything to point me in the right direction will be highly
appreciated

Answer 1

Here is another trick to solve your problem,
function custom_filter($array) {
$temp = [];
array_walk($array, function($item,$key) use (&$temp){
foreach($item as $value)
$temp[] = $value;
});
return $temp;
}
array_walk — Apply a user supplied function to every member of an array
Here is working demo.

Answer 2

here you go
$result = [];
foreach($array as $arr)
{
$result = array_merge($result , $arr);
}
var_dump($result);

Answer 3

Like this:
$i=0;
foreach ($array as $n1) {
foreach ($n1 as $n2) {
$newArr[$i]['title']=$n2['title'];
$newArr[$i]['title_num']=$n2['title_num'];
$newArr[$i]['status']=$n2['status'];
}
$i++;
}
Or simpler as suggested in the comments
for ($i=0; $i < count($array); $i++) {
foreach ($array[$i] as $n2) {
$newArr[$i]['title']=$n2['title'];
$newArr[$i]['title_num']=$n2['title_num'];
$newArr[$i]['status']=$n2['status'];
}
}
