I have below code in my laravel application controller:
$levels = $request->level;
return $levels;
and it returns like this:
{
1: [
"9226"
],
2: [
"166"
]
}
which I need is return just values (9226,166) as array like below:
{
"9226",
"166"
}
How to get just values?
if array then you can use array_flatten()
array_flatten($levels)
if it is collection then
$ar = $levels->flatten();
$ar->all(); // get array
You can use array_values function to get the values from the array. As your function is returning an a object so you need to convert that to array and then use the array_values
Ex.
$levels = array_values((array)$levels);
Use Laravel's Collection. For example:
$level = [1 => ["9226"], 2 => ["166"]]; // or $request->level;
dd(
array_flatten($level),
collect($level)->flatten()->toArray()
);
array_merge(...$levels);
You can use array_merge to flatten 2D arrays as of PHP 5.6 with the use of the splat operator (...).
** edit:
{
1: [
"9226"
],
2: [
"166"
]
}
Is an object, which as Ashok Gadri has mentioned, which you will need to convert to an array before using array syntax.
flattenmethod of laravel directly$levels->flatten();it will solve your problem$request->levelalso suggests it is not a collection.flattenarray using laravel builtin method$levels = collect($request->level);return $levels->flatten();
