Answer 1

You can use Laravel helper function array_flatten for this:
$array = [
0 => [
0 => 'Women',
],
1 => [
0 => 'children',
1 => 'smile',
],
2 => [
0 => 'Abstract',
],
3 => [
0 => 'Lion',
1 => 'Cheetah',
],
];
$result = array_flatten($array);
var_dump($result);
Output:
array (size=6)
0 => string 'Women' (length=5)
1 => string 'children' (length=8)
2 => string 'smile' (length=5)
3 => string 'Abstract' (length=8)
4 => string 'Lion' (length=4)
5 => string 'Cheetah' (length=7)

Answer 2

Try this:
foreach ($old as $data) {
foreach ($data as $value) {
$new[] = $value;
}
}
print_r($new);
}
In first foreach you are getting array inside array and in second foreach you will get the value. Insert these values in new array to get desired result. Use print_r to see the result

Answer 3

Simply you can use : call_user_func_array
<?php
$array = array (
0 =>
array (
0 => 'Women',
),
1 =>
array (
0 => 'children',
1 => 'smile',
),
2 =>
array (
0 => 'Abstract',
),
3 =>
array (
0 => 'Lion',
1 => 'Cheetah',
),
);
$result = call_user_func_array('array_merge', $array);
print_r($result);
?>
Output :
Array
(
[0] => Women
[1] => children
[2] => smile
[3] => Abstract
[4] => Lion
[5] => Cheetah
)

Answer 4

Since Laravel 5.7 the syntax is Arr::flatten($array) so that now it looks like
use Illuminate\Support\Arr;
$array = [
0 => [
0 => "Women"
],
1 => [
0 => 'children',
1 => 'smile'
],
2 => [
0 => 'Abstract'
],
3 => [
0 => 'Lion',
1 => 'Cheetah'
]
];
Arr::flatten($array);
Output :
array:6 [
0 => "Women"
1 => "children"
2 => "smile"
3 => "Abstract"
4 => "Lion"
5 => "Cheetah"
]
