During development, the developer needs to go through loops to prepare a single dimensional array out of a multi-dimensional array.

Laravel provides many helpers which come handy in multiple ways and saves developers work.

One of such isArr::flatten() which flattens a multi-dimensional array into a single level by default.

Tested with Laravel versions5.8,6 and7.

We need to importIlluminate\Support\Arr namespace withuse keyword.

Kindly check for your version on the official DOC forLaravel Helper Arr::flatten(). This link will take you toLaravel 7 Documentation.

Syntax

Arr::flatten(array$array,[int$depth=INF])

Parameters

\$array (necessary)

• The first parameter is necessary and must be anarray that needs to be flattened.
• Laravel will extract elements and provides us with a new single dimension array based on the depth parameter.

\$depth (optional)

• The second parameter specifies the depth and it's an optional parameter.
• This value must be an integer type.
• The depth specifies how deep a nested array should be flattened.
• The default value for depth is infinity(INF) from which Laravel will extract elements and provides us with a new single dimension array.

Return value

It returns a new 1-D flattened array.

Example

$data=['country'=>'India 🇮🇳','languages'=>['Gujarati','Hindi','Sanskrit','Tamil','Urdu',],];dd(Arr::flatten($data));

Output

array:3 [  0 => "India 🇮🇳"  1 => "Gujarati"  2 => "Hindi"  3 => "Sanskrit"  4 => "Tamil"  5 => "Urdu"]
