[0] => Array
    (
        [0] => Women
    )

[1] => Array
    (
        [0] => children
        [1] => smile
    )

[2] => Array

    )
)

I want output something like this:-

$getKeywords =  DB::table('contributor_images')->select('keywords')->get();
$getKeywords = json_decode(json_encode($getKeywords),true);
    foreach($getKeywords as $keyword){
        $AllKeywords[] = $keyword['keywords'];
    }
    foreach ($AllKeywords as $key => $ExplodeKeywords) {
        $searchkeywords[] = explode(',',$ExplodeKeywords);
    }
    echo "<pre>"; print_r($searchkeywords); die;

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)

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

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
)

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"
]
