Laravel check if string is included in array of strings

I’m trying to determine if a String is included in a array of strings in Laravel.

I have

$rol = 'Admin';
$roles = ['Admin', 'Guest'];

I want to know if $rol is included in $roles without looping.

In Javascript it would be something like this

let array = ['Admin', 'Guest']
let role = 'Admin'
array.includes(role)

If I do this in Laravel, there are some cases I’m not expecting:

Str::contains($rol, $roles) //Output would be true

But if now $roles = ['dmin', 'Guest'] instead of ['Admin', 'Guest']

Str::contains($rol, $roles) //Output would be true but I'm expecting false as 'Admin' is not a $roles element

    You should not use Str::contains which checks if the string contains (e.g. has a substring) any of the provided values, but Collection contains, e.g. collect($roles)->contains($rol).

    • use in_array function from php.
      For example:
    $rol = 'Admin';
$roles = ["Admin", "Guest"];

if (in_array($rol, $roles)) {
    // Matches
}
else {
    // Not matches
}

    You can also convert the array to the type collection which is brought to your by Laravel framework. Just simply pass the array to the function collect(). For example:

    $rolesCollection = collect($roles);

    After that apply any conditions which are applicable to the collection type.

    Laravel has a lot of helper methods. The one you’re likey after is the Arr::has method:

    $role = 'Admin';
$roles = ['Admin', 'Guest'];

$contains = Arr::has($role, $roles);

    This method is particularly handy when working with nested arrays. Using dot notation you can perform the same lookup without having to write that logic yourself.

    Try this one, it’s not Laravel but PHP.
    use stripos function.

    $rol = 'Admin';
$roles = ['Admin', 'Guest'];
if (stripos(json_encode($roles),$rol) !== false) {
   echo "Found It!";
}
